The ecuation "2H2O ----> 2H2 + O2" means that for every 2 mol of water, 2 mol of hydrogen and 1 mol of oxygen is produced. That means that if you start with 2 mol of water, 2 mol of hydrogen is going to be produced (the ratio is 1:1)

with the relationship 2H20--- 2H2 + O2 u produced 2 moles of hydrogen but when u are required to get the gram moles u need to multiply the coefficient with the subscript so it will yield 4H

Each mole of water has 6.022 X 10^23 molecules of water (Avogadro's number). Each molecule of water gives 2 atoms of hydrogen, that is 2 moles of hydrogen. So, 2 moles of water will give us 2 times 2, that is 4 moles of hydrogen.

2H2O----> 2H2 + O2
Number 2, in front of H2, says that there are 2 moll of hydrogen. So, 2 moll of hydrogen are produced. I guess.
Send me answer on an email, when you solve it. (if this is not correct). My mail is tarav92@yahoo.com

according to stoickiometry nH20/2= nH2/2 = NO2
so 1 mol

This is not the correct reaction, the correct is
H20----->H2+OH (Balance it).
