Question

Why is the amount of gas collected in one of the test tube in activity 1.7 double of the amount collected in other name the gas?

Answer 1

Explanation:

Since the hydrogen and oxygen combine in the ration 2: 1 to form a water molecule, the amount of hydrogen gas is doublethat of oxygen.

Answer 2

$<i> Water contains two parts of hydrogen and one part oxygen. Therefore, during the electrolysis of water the amount of hydrogen gas collected in one of the test tubes is double than that of the oxygen produced and collected in the other test tube.$
