Solution

(a) Methane gas is evolved having the molecular formula $C H_{4}$ .
(b) $C H_{3} C O O N a + N a O H C a O \to N a_{2} C O_{3} + C H_{4}$
(c) The methane gas is collected by the downward disacement of water.
(d) We know that methane is a saturated hydrocarbon. Thus, being saturated it does not react with nitric acid.
