You are given the following materials: (i) Iron nails (ii) Copper sulphate solution (iii) Barium chioride solution (iv) Copper powder (v) Ferrous sulphate crystals (vi) Quicklime Identify the type of chemical reaction taking place when: (a) Barium chloride solution is mixed with copper sulphate solution and a white precipitate is observed. (b) On heating copper powder in air in a china dish, the surface of copper powder turns black. (c) On heating green coloured ferrous sulphate crystals,reddish brown solid is left and smell of a gas having odour of burning sulphur is experienced. (d) Iron nails when left dipped in blue copper sulphate solution become brownish in colour and the blue colour of copper sulphate fades away. (e) Quick lime reacts vigorously with water releasing a large amount of heat. Write chemical equations for each one of the above reactions
