Chemistry Form 4: Chapter 7 - Titration Method

The technique of titration is used to find out accurately how much of a chemical substance is dissolved in a given volume of a solution, that is, the concentration of the solution.

The technique uses a set of apparatus with which volumes of solutions can be measured to an accuracy of greater than 0.1 cm3. Three important pieces of apparatus are:
  • Burette - Measures accurately the volume of a solution added. Readings can be taken to an accuracy of half a division.
  • Pipette - Delivers an accurate volume of a solution. Often this is 25 cm3.
  • Volumetric flask - Used to make up an accurate volume of a solution, for example, 250 cm3. This could be a standard solution (of exactly known concentration and known solute). 

    Heaven Photographed by Hubble Space Telescope

    Heaven 3 Billion Light Years Away Hubble Telescope Pictures

     WASHINGTON, DC – Despite new repairs to the Hubble Telescope, NASA refuses to release old photos or take new ones of Heaven!
    In 1994, a researcher was smuggled one top-secret photo the Hubble Space Telescope had taken of what is presumed to be Heaven. Weekly World News was the first to print the image and report on Dr. Masson’s findings, but despite the media coverage, NASA refused to acknowledge the existence of the photo.

    Now that the Hubble has been repaired and NASA is officially releasing some of it’s new findings, the Weekly World News editorial team believes it is NASA’s responsibility to further investigate this space anomaly!

    Just days after space shuttle astronauts repaired the Hubble Space Telescope in mid December, the giant lens focused on a star cluster at the edge of the universe – and photographed heaven!

    That’s the word from author and researcher Marcia Masson, who quoted highly places NASA insiders as having said that the telescope beamed hundreds of photos back to the command center at Goddard Space Flight Center in Greenbelt, Md., on December 26.

    The pictures clearly show a vast white city floating eerily in the blackness of space.And the expert quoted NASA sources as saying that the city is definitely Heaven “because life as we know it couldn’t possibly exist in icy, airless space.“This is it – this is the proof we’ve been waiting for,” Dr. Masson told reporters.

    “Through an enormous stroke of luck, NASA aimed the Hubble Telescope at precisely the right place at precisely the right time to capture these images on film. I’m not particularly religious, but I don’t doubt that somebody or something influenced the decision to aim the telescope at that particular area of space.

    “Was that someone or something God himself? Given the vastness of the universe, and all the places NASA could have targeted for study, that would certainly appear to be the case.”

    NASA spokesmen declined to comment on the author’s report “pending further analysis of the photographs received on December 26.” In spite of official silence, agency insiders concede that NASA “has discovered something that might alter the future of all mankind.”

    They also confirmed that President Bill Clinton and Vice President Al Gore have taken a keen personal interest in the photographs and have requested daily briefings. Dr. Masson said: “The Hubble Space Telescope was designed to photograph images as far away as the edge of the universe but a lens flaw prevented it from doing so until shuttle astronauts corrected the defect during a recent mission.

    “When they finished their work, the telescope trained its enormous glass eye on the outer reachers of the universe.“From what I understand, the first images it received were nothing more than kaleidoscopic bursts of color and light.“As adjustments were made and the focus sharpened, NASA analysts couldn’t believe their eyes.“After checking and rechecking the data, they concluded that the images were authentic. They also theorized that the city couldn’t possibly be inhabited by life as we know it.

    “The only logical explanation was that the city was inhabited by the souls of the dead. As one of my sources put it, ‘We found where God lives.’”It has been rumored that the space agency has forwarded photographs to Pope John Paul II at his request, but Vatican sources will neither confirm nor deny it.

    Dr. Masson, who obtained copies of a single photograph from her NASA sources, says the space agency’s next move “will be most revealing.”
    “This is a chance for NASA to come clean with the public and tell us everything it knows,” she said.

    Physics Form Five: Chapter 5 - Nuclear Fusion

    Fusion is what happens when two atomic nuclei are forced together by high pressure and high temperature ... high enough to overcome the strong repulsive forces of the respective protons in the nuclei. When the nuclei fuse, they form a new element, and release excess energy in the form of a fast-moving neutron. The energy is 'extra' because the mass of the newly formed nucleus is less than the sum of the masses of the original two nuclei; the extra mass is converted to energy according to Einstein's equation E=mc2 . This energy can be used to do useful work!

    Deuterium can be easily extracted from seawater, where 1 in 6500 hydrogen atoms is deuterium. Tritium can be bred from lithium, which is abundant in the earth's crust. In the fusion reaction a deuterium and tritium atom combine together, or fuse, to form an atom of helium and an energetic neutron.
    Fusion is like lighting a match to a bucket of gasoline. You need that input energy (the match), but what you get as a result is far more powerful. Fusion fuel is very energy dense. A thimbleful of liquid heavy-hydrogen fuel could produce as much energy as 20 tons of coal. Or, more realistically, one pick-up truck full of deuterium would release the energy equivalent of approximately 2 million tons of coal (21,000 rail car loads), or 1.3 million tons of oil (10 million barrels), or 30 tons of Uranium Oxide (1 rail car load). Clearly, with seawater as our energy source, our energy problems would be over forever!

    Man torches self after ‘burning’ lottery win

    A VEGETABLE farmer who lived a life of luxury after winning almost RM1mil in a lottery five years ago torched himself when his “pot of gold” became empty.The 63-year-old from Serian, Sarawak, known only as Khoo, was reported to have dug a “grave” at the back of his house before splashing petrol on his body and lighting it, reported Berita Minggu.

    The man had won more than RM750,000 five years ago and then reportedly spent up to RM1,800 on a single bet over the years, hoping to strike it big again, the weekly said. Serian OCPD Deputy Supt Jamali Umi said the police have classified the case as sudden death.

    He said the victim’s nephew had found the man dead in the hole. A relative, who declined to be named, said Khoo, who never married, had stopped cultivating his farm upon winning the lottery and had spent the money on a new house and several vacations. But with no new winnings, the barrel soon became empty.
    What will you do when you had won RM 750,000 lottery? From the news you have read above, human greediness for money has taken the life of this old man. It is meaningless when someone lost his life for the love of money. When you are born into this world, you came empty-handed. Likewise, when you leave this world, you also go empty-handed and furthermore, you will have to face God's judgement for what you have done in the world.

    Money is just a human creation tool to survive in this world. Do not get me wrong! Money is not an evil but the love for money is the root of all evil. If you love money more than God, evil will come and destroy your life. At the end, you have to answer to God. God is a faithful provider and He will bless you abundantly if you are obedient in His eyes. God will also make some of you rich according to His purpose. But not everyone will become rich because not everyone can handle and manage huge money well. Let me describe money as a very sharp sword. If you cannot handle the sword efficiently, the sword might one day hurt and harm you terribly, just like what happened to this old man. Being rich is meaningless if you do not know how to use your wealth to bless others.

    "Money will buy you a bed but not sleeps, books but not brains, food but not appetite, medicine but not health, luxury but not culture, amusement but not happiness, a crucifix but not a Saviour!"

    Love for $$$ = Root of all evil
    Be obedient to God = Abundant Blessing

    You cannot serve two masters!
    You have to choose either one!

    Physics Form Five: Chapter 5 - Nuclear Fission

    Beware! Nuclear fission was applied in making the first atomic bomb that dropped on Hiroshima city, Japan during the World War 2.

    SPM, PMR Exam is coming,!

    The patterns are used to test the level of stress a person can handle. The slower the pictures move, the better your ability of handling stress. Alleged criminals that were tested see them spinning around madly. However, senior citizens and kids see them standing still. None of these images are animated - they are perfectly still..

    Are you ready for the stress test?
    How about this one?
    Don't worry-lah, enjoy your exam.

    Science: Pregnancy and Foetal Development

    Every human being begins life as a single cell, formed when father's sperm fertilises mother's egg. Fertilisation normally takes place in the mother's Fallopian tube, which connects the uterus (womb) with the ovary.
    When fertilisation is completed and the nuclei of egg and sperm have combined, a new being comes into existence and is capable of further development, marks the beginning of the human lifespan.

    • placenta - a temporary organ within the uterus which transfers nourishment and oxygen from the mother, removes waste products from the baby through diffusion process.

    • amniotic fluid - protects the developing baby by cushioning against blows to the mother's abdomen, allows for easier fetal movement, promotes muscular/skeletal development, and helps protect the fetus from heat loss.

    • umblical cord - to carry nourishment and oxygen from the placenta to foetus and return waste products to the placenta from the foetus.

    After witnessing the animation video, we know that there is a life created by God. Therefore, 
    Abortion = Murder = Sinful Act

    Principal Shouldn't Utter Racist Remarks

    What a sad day for Malaysia education system when a secondary school's principal uttered such racist remarks to non-bumi students during the launch of Merdeka celebration at school level. I was shocked when I learn this news from The Star. Being a school head, she should promote unity and harmony among the students regardless of their race, religion and social background. Racism should not exists in school. We are all the same as MALAYSIAN, unite and live harmoniously in our beloved Tanahair. We may have differences but we respect each other religion, culture and custom in our society. Teacher roles not only in teaching but also to nurture good values such as peace, love, respect, and unity in student life.

    I have been teaching at my present school for 8 years and most of the students I taught are mainly from bumiputera, almost 98%. They are not academic-inclined and some of them are problematic. This is the main reason why their parents send them to my school to learn vocational skills. I am a chinese teacher teaching them science subject. As you know, majority of these students dislike science subject. I have to be very strict with them in their studies so that they are able to score good grade. Consequently, I was being complained by the students due to strict teaching. The whole class went to the PK HEM office demanding to change science teacher. In a particular year of teaching, there was a case where I was being labelled as anti-malay by a student's parent. I was sad but this event did not hinder me to continue teaching my students with love. I explained to them why I have to strict with them. When they came back to school to take their SPM result, they thanked me for being strict to them, "Cikgu tegas dengan kami, barulah kami boleh score".

    I never blame them but I choose to forgive them. Students particularly in their teen age still haven't reach rationale and mature thinking yet. They are immature and that's why teacher plays a vital role to nurture and cultivate good values in their thinking. If I practicing racism in classroom, how my bumiputera students were able to score science subject, furthermore majority of them did not attend outside tuition class. I believe all religion forbid us to be racist. Only unethical politicians play racial card for their own agenda and survival. Religion teaches us to love one another. Let's we say no to racism whether you are teacher or student.

    School head under probe over racist remarks

    KULAIJAYA: Police are investigating a school principal who allegedly used racist remarks against non-Malay students during a Merdeka celebration at the school here recently.Kulaijaya deputy OCPD Asst Supt Mohd Kamil said police had received 12 reports against the principal since Saturday and that the case was being investigated under Section 504 of the Penal Code.Over 50 parents and students had lodged the reports against the principal, who allegedly described the non-Malays as “penumpang” (passengers) in the country during her speech at the start of the celebration on Aug 12.

    “This is not the first time that she had made racist comments against Chinese and Indian students in our school,” said 17-year-old student Brevia Pan.She added that the principal, who joined the school early this year, would only target Chinese and Indian students.“During the Merdeka celebration, she had told non-Malay students to go study in a Chinese school or go back to China,” she told reporters in a press conference organised by Senai assemblyman Ong Kow Meng.Another student, Ashvini Thi-na­karan, 17, said many Malay students were influenced by the principal’s remarks and made similar comments and called them names.

    “Before she came to my school, all the students got along well,” she said. Her father R. Thinakaran, 47, said this was a serious matter and that principals should not behave like this.“This principal has caused racial disharmony at the school,” he said, adding that if no action was taken, he would take his daughter out of the school.

    Big, Bigger, Biggest,.........Really very BIG!

    If you think you are very big and smart, then think about these stars shown on video. You will humbly realize that GOD is so great and magnificient with His created universe.

    So, next time don't be so arrogant-lah. Be humble always. Of course-lah, teachers in school also need to learn how to be humble. Perhaps, by this way, students will respect teachers wholeheartedly. Even God is so humble to save us....

    Life Long Learning....

    Wow! I really salute this retired HM's determination and hard work to complete his studies in law. Even at this age of 62, it is not an easy subject to learn cause learning law needs a powerful memory. Really tabik you......! I wish I could be like him to pursue my dream to become doctor one day. This dream has been planted in my mind when I was in Form Four, but to my dismay, I failed to realize it. Now, I become doctor in healing student's result. Ha..ha...ha....What a wonderful job? Doctor earns big buck of money but teacher only earns peanut. Furthermore, people around you respect doctors more than teachers.


    When I retire one day, I doubt whether my eyes still can function properly or not to operate patient's organ. I think I better drop this pursuit and find another area to work for. Any suggestion from you........ I want to be like him(retired HM) to pursue knowledge until my last breath. 

    Please Read the true story below:

    Retired HM called to the Bar

    KUALA LUMPUR: Yap Mia Lee has been an educator for more than three decades and his word was the law in the Chinese primary school where he was headmaster. After retirement, he decided to study law.He was one of two retirees who were called to the Malaysian Bar yesterday.

    Yap, 62, and S. Jayaram, 59, were admitted as advocates and solicitors of the High Court of Malaya after successfully completing their law degrees, certificates in legal practice (CLP) and chambering.For Yap, who has been in education for 34 years, it was a case of following his daughter Hsu Lyn’s footsteps in becoming a lawyer.Even better, their roles were reversed when he did his chambering at her firm here, and his 36-year-old daughter became his pupil master.

    “After I retired in 2004, I decided to take up law to keep my mind active and to keep myself busy. I am really happy and excited,” said Yap.
    His whole family turned up for the occasion and his wife Su See Kek, 62, said she was “very proud of him”.

    Science Form Three: Chapter 9 - Formation of Stars

    The formation of stars takes place within large clusters of dust and gas. These low density clouds of gas in which a star is born are called nebulae.The clouds, which are mostly composed of hydrogen, collapse in on itself, due to gravity.
    This slow process can be quickened by a passing star or shockwave from a supernova. As the cloud collapses, it starts to swirl. Over millions of years, more hydrogen gas is pulled in the spinning cloud. The collisions, which occur between the hydrogen atoms, start to heat the gas in the cloud. Once the temperature reaches 15, 000, 000 degrees celcius, nuclear fusion may begin in the core.

    Nuclear fusion occurs when atoms fuse to form an element with larger atoms, releasing large amounts of energy. In this case, nuclear fusion will form the heavier element, Helium. This causes the cloud to glow and form a protostar. The protostar will stop collapsing at this point because of the energy surge from fusion, which flows out of core, stopping its collapse. The protostar will continue to gain mass (which varies depending on the matter available in the nebula), until it is stabilized. At this point the protostar will become what is known as a main-sequence star, which may last millions and maybe even billions of years to come.

    Some examples of nebulae:

    The more you give, the more blessing you gain...

    Billionaires Bill Gates and Warren Buffett want other American billionaires to give at least half their wealth to charity.Gates and Buffett are calling their campaign The Giving Pledge. Buffett, chairman and CEO of Berkshire Hathaway Inc., said in a letter introducing the concept that he couldn't be happier with his decision in 2006 to give 99 percent of his roughly $46 billion fortune to charity.

    Billionaires pledge $125 billion to Bill Gates charity drive
    Forty American billionaires have pledged at least half of their wealth to charitable causes - a combined value of at least $125 billion.The offerings came at the request of some of the country's best-known billionaires, Bill and Melinda Gates and Warren Buffett. The trio worth a combined $100 billion convinced 40 families and individuals on the Forbes 400 list of richest Americans to sign onto their Giving Pledge campaign.

    Included on the list of donors, which was released Wednesday, are California hedge fund investor Thomas Steyer and his wife, Kat Taylor, who were worth around $1.2 billion in 2008.Mr. and Mrs. Gates and Mr. Buffett, first and second respectively on the Forbes 400 list, reached out to between 70 and 80 of the Forbes list’s members and around half agreed to pledge. The 40 families and individuals who have joined the Giving Pledge are worth a combined $251 billion, according to recent figures from Forbes.

    According to the Merrill-Capgemini 2010 World Wealth Report, North America's wealthiest donate about $200 billion annually. That figure comes from charitable contributions from people making $1 million or more.“In the case of money, you can’t spend it [all] if you have over a certain amount," said New York City Mayor Michael Bloomberg, who is also on the list, and is worth about $18 billion. I’ve always thought the best thing to do is to make the world better for your kids and your grandkids rather than just give them some money.”
    I really salute these two world's richest man and world's best philanthropist for their care about charity work. They almost donated all of their wealth to charity instead giving it to their children. Their philosophy is give enough to children so that they are able to work themselves with the available resources. 

    How about us whose are not rich like them? Can we also donate something to charity? Yes, we can! We are not rich like them but we also possess talents and gifted skills. We can do charity in the form of rendering our service, time, energy and talent to the needy community. What ever good work you done, it counts in God's mind. The more you give to others, the more blessing will pour upon you. One of the way to gain financial prosperity is to give first.

    Chemistry Form Four: Chapter 6 - Displacement of Metal from Salt Solution

    Electrochemical series can be constructed by using displacement reaction of metal from salt solution. A more electropositive (reactive) metal can displace a less electropositive metallic ion (less reactive) from its salt solution.

    For example:  Reaction between magnesium and copper (II) sulphate produces copper and magnesium sulphate.
