2. it's an exothermic reaction
3. due to corrosion (rust)
4.metallic ores are reduced to obtain metals from them
5. Hydrated Copper Sulphate crystals [CuSO4.5H2O] are blue in colour. When copper sulphate crystals are heated strongly, they loose all the water of crystallization and form anhydrous copper sulphate [which is white in colour]. The water of crystallisation gives the crystals of their salts their shape and colour.
6. photolytic decompostion or photolysis
