Write correctly balanced equations in the following cases :

(a) When lead (II) oxide (PbO₂) is heated.

(b) When phosphorous is burnt in a jar of oxygen.

Give a reason for the following :

Like oxygen, nitrous oxide (N₂O) also supports combustion. A glowing splint introduced into a jar of N₂O, is rekindled.

Give a chemical test to distinguish oxygen from N₂O
