Why is the amount of gas collected in on...

Why is the amount of gas collected in one of the test tubes in activity 1.7 see tesxtbook double of the amount collected in the other ? Name this gas

Text Solution

Verified by Experts

It is because in water , hydrogen is two times than oxygen by mass and volume.
`2H_(2)Ounderset("Current")overset("Electric")rarr2H_(2)+O_(2)`
`H_(2):O_(2)`
