sulphur its physical and chemical properties and uses

Nuclear Energy and Chemical Energy - Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process of changing mass into energy pr..

A e is called Faraday constant (or Faraday) and denoted by F. From the measured values of F = 96,487 C/mol (from experiments on electrolysis) and of N A = 6.02 x 10 2 3 /mol (from experiments on Brownian motion), e is estimated to be 1.6 x 10 - 1 9 C. In electrochemical cells, chemical..

Appliances used in our day to day life are based on the principles of electricity and magnetism. Electricity is one of the most important sources of energy. Lights, fans, motors, radios and television are some common appliances which work on electricity. Benjamin Franklin Historically, it..

Source of Electricity - Electrons in different metals can have different energies. If two of these metals are placed in a conducting liquid (electrolyte) a difference in electrical potential is set up between them. A pair of different metals arranged in this way is an electrochemical cell. It conve..

The electrons thus released move to the zinc rod via the external circuit. The ammonia gas so produced escapes. The hydrogen ions diffuse through the porous pot and interact with MnO 2 . (The charcoal powder makes MnO 2 electrically conducting.) Therefore, These positive charges are giv..

The fact that chemical changes produce electrical effect was discovered accidentally in 1971, by Luigi Galvani, an Italian professor. He found that an electric current flowed across two dissimilar metals. Volta, professor of natural philosophy successfully reproduced some of Galvani's res..
