Explanation:
Detailed explanation-1: -Water undergoes decomposition during electrolysis and forms hydrogen and oxygen gas in the ratio 2:1 by volume. The reaction occurs as follows: 2H2O→2H2+O2.
Detailed explanation-2: -2H2(g)+O2(g)⟶2H2O(l) is the correction reaction as during formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.
Detailed explanation-3: -A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.
