The gas collected in one tube which is double is hydrogen . It is double because the hydrogen and oxygen are in ratio of 2:1 which mean that there need to be 2H atoms for every one 1 Oxygen atom . This is justified by law of constant proportions.

water has hydrogen and oxygen in the ratio 2:1
so 1 volume of oxygen is released at anode When two volumes of hydrogen is released at cathode
