Solution

Sodium (Na) and potassium (K) react with cold water to from basic salt NaOH and KOH respectively. The molecular mass of NaOH is 40. So, X is Na and Y is NaOH. The gas liberated during the reaction is hydrogen $(H_{2})$ . So Z is $H_{2}$ .
$2 N a + 2 H_{2} O \to 2 N a O H + H_{2} +$ Heat energy
