essay on the theme of lord of the flies - This GCSE Chemistry quiz is all about one of the fundamental parts of science - chemical reactions. Chemical reactions are changes to the arrangement of atoms and the molecular structure of materials. They are all around us. We can see some reactions such as fireworks and explosions. Many are very useful, like cooking and combustion. Describe the combustion of hydrogen When hydrogen reacts with oxygen, there is a loud pop, a flame for a split second, and then it's all over. Hydrogen can be produced by reacting a metal with an acid, i.e. magnesium with sulphuric acid. The products of combustion of hydrocarbons can be tested in the lab using the set up shown below: When the fuel, like alcohol, in the spirit burner is burning, the water vapour produced condenses and turns back into liquid water when it passes through the beaker of ice. maths and science from year 1 to GCSE.
