Answer
In Activity 1.7, electrolysis of water is carried out and the products obtained are hydrogen and oxygen. As water contains 2 parts of hydrogen element as compared to only 1 part of oxygen element, hence, the amount of hydrogen gas collected in one test tube is double of the amount of oxygen gas collected in the other test tube.
