These fuels undergo nuclear fission in nuclear reactors and emit power. The greatest producers of nuclear power are U.S.A. and Europe. In India at Rajasthan, and Jharkhand have large deposits of Uranium. Thorium is found in large quantities in the Monozite sands of Kerela.

The chemical decomposition produced by passing an electric current through a conducting liquid is called electrolysis.

Take out carbon rods carefully from two discarded cells. Clean their metal caps with sand paper. Wrap copper wires around the metal caps of the carbon rods and join them to a battery. These two rods are electrodes.Now, pour a cupful of water in a glass/plastic bowl and add a teaspoonful of salt or a few drops of lemon juice to water to make it more conducting. Immerse the electrodes in this solution. Make sure that the metal caps of the carbon rods are outside the water. Wait for 3-4 minutes. We will see that the bubbles of gases are produced at the two carbon electrodes. The formation of gas bubbles at the two carbon electrodes shows that a chemical change has taken place in water on passing electric current through it.

The Bhopal gas leak that killed at least 2,000 people resulted from operating errors, design flaws, maintenance failures, training deficiencies and economy measures that endangered safety, according to present and former employees, company technical documents and the Indian Government's chief scientist. The disaster happened because water entered a tank containing Methyl isocyanate. This caused a chemical reaction which resulted in the buildup of much Carbon dioxide, among other things. Immediately after the disaster, UCC began attempts to dissociate itself from responsibility for the gas leak. ... In March 1985, the Indian government enacted the Bhopal Gas Leak Disaster Act as a way of ensuring that claims arising from the accident would be dealt with speedily and equitably.

No,the victims of Bhopal Gas Tragedy did not got justice as the government gave a compensation of rs.5000 which was too less many victims still suffer from blindness and several disorders.Also till date many chemical compounds are lying where the Union Carbide plant was established this all led to the carelessness and poor pipeline which leaked the harmful pesticides and gases from the plant.
