Question

why is the amount of gas collected in one of the test tubes in activity 1.7 double of the amount collected in the other name this gas

Answer 1

$\huge \bf \green \{answer$
water contain two parts hydrogen and one part of oxygen. therefore the amount of hydrogen and oxygen produced during electrolysis of water 2 : 1 during electrolysis is hydrogen goes to one test tube and goes to another amount of gas collected is one of test tube is double of the amount collected in other.

Answer 2

Answer:

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

The chemical equation for the electrolysis of water is:

2H2O(l) →2 H2(g) + O2(g)

It is evident from the equation that 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.

Hence, the name of the gas is Hydrogen.
