Oxygen would be in excess, water's chemical formula is H2O. You need 2 atoms of hydrogen for every atom of oxygen. So you could make 10 molecules of water with 10 atoms of Oxygen left over.

20 molecules H + 20 molecules O = H20
Hydrogen will be in excess. Oxygen will use up all the molecules of its own way faster than hydrogen because of its density

oxygen will be in excess. H2O
takes two molecules of hydrogen and 1 molecule of oxygen
so you will have 10 molecules of oxygen left over

Oxygen.
A molecule of water (H2O) requires two molecules of hydrogen and one of oxygen, so with twenty of each, you would still end up with some leftover oxygen.
God bless.

oxygen is in excess
all 20 hydrogens would be used, and only 10 oxygens, leaving 10 oxygens

Oxygen for every 2 Hydrogens you need one oxygen. Hince H2O.

H20 so oxygen would have 10 left at the end

Actually you would need 40 molecules of oxigen.

2H2 + O2 = > 2H2O
since 2 moleculas of hydrogen react with 1 one of oxygen
20 ------------------------------------------------10 moleculas of oxygen
Oxygen will be in excess
