A metal X on heating burns in air to form $X_{2} O_{3}$ . Another metal Y burns in air only on strong heating to form $YO$ . The oxides so formed ( $X_{2} O_{3}$ and $YO$ ) can react with Hydrochloric acid as well as with Sodium hydroxide solution to form the corresponding salts and water.

Q. Q1. Answer the following
(A) A metal 'X' reacts with dilute hydrochloric acid to form a gas 'Y'. The metal 'X' also reacts with sodium hydroxide solution ( on heating) to form the same gas 'Y' . When a lighted matchstick is applied, this gas burns with a 'pop sound'. On the other hand the metal 'Z' does not react with dilute hydrochloric acid even on heating but it reacts with conc. Sulphuric acid.
