Question

when a metal X is treated with cold water, it gives a basic salt Y with molecular formula XOH and liberated a gas Z, which easily catches fire. identify X, Y and Z and also write reaction involved​

Answer 1

Answer:

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

). So Z is H
