Answer:
1 The reaction given in the question is forming ammonia gas. This process is known as the Haber process. The Haber Process - The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic.

3 Answer. quicklime is acidic which is corrosive in nature and as u know when an acid is poured on a surface it corrodes the surface so when u put it in water it will get hot.
4 If a copper carbonate is heated with carbon, a chemical reaction takes place. Initially the copper carbonate thermally decomposes into copper oxide. Then the carbon reacts with the copper oxide liberating pure metal in a type of displacement reaction.
