Question

lwhy 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

Answer:

Activity 1 .7 is electrolysis of water.

During electrolysis of water , the water made up of 2 hydrogen molecules and an oxygen molecule , is obtained in the same molar ratio. Hence , one gas is double of the other. So , this gas is hydrogen.

Answer 2

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