(b) Give equations for the reactions.
(c) How is hydrogen separated from carbon dioxide and carbon monoxide ?
Write a balanced chemical equation for each of the following :
1. Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide.
2. Calcium hydride reacts with water to form calcium hydroxide and hydrogen gas.
3. Methyl alcohol burns in air to form carbon dioxide and water.
4. Liquid hydrogen peroxide decomposes to give water and oxygen gas.
5. Aluminium hydroxide reacts with sulphuric acid to give ammonium sulphate and water.
6. Aluminium sulphate solution reacts with sodium hydroxide to form a precipitate of aluminium hydroxide.
Write the balanced chemical equations for the following reactions- (a) Sodium carbonate on reaction with hydrochloric acid in equal molar concentration gives sodium chloride and sodium hydrogen carbonate. (b) Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide. (c) Copper sulphate on treatment with potassium iodide precipitates cuprous iodide (Cu2I2), liberates iodine gas and also forms potassium sulphate.
