When water is electrolyzed, two gases ar produced. As indicated in the chemical equation, twice the volume of one gas is produced compared to the other.
a) Which gas is produced in larger quantities? Explain
* I think it's hydrogen, but i am not sure why we need more hydrogen.
b)How could you test the gases to confirm your choice?

1. the formula for water is H2O. Therefore, two atoms of hydrogen are released for each atom of oxygen. You could test the gases by putting them in a balloon and seeing which one floats.
