What type of chemical reaction stake place when:
(a) A magnesium wire is burnt in air?
(b) Lime-stone is heated?
(c) Silver bromide is exposed to sunlight?
(d) Electricity is passed through water?
(e) Ammonia and hydrogen chloride are mixed?

(a) Combination reaction, since magnesium reacts with oxygen in this reaction.

(b) Decomposition reaction, since on heating limestone decomposes to give calcium oxide and carbon dioxide.

(c) Decomposition reaction, since silver bromide decomposes to give silver metal and bromine gas.

(d) Decomposition reaction, since water on being passed on by electricity, decomposes to hydrogen and oxygen.

(e) Combination reaction, since ammonia and hydrogen chloride combine to give ammonium chloride and hydrogen.
