How much hydrogen and oxygen must react to produce 65.00 grams of water?
2H + O2 -> 2H2O
You need to correct the equation.
2H2 + O2 ==> 2H2O
65.00 g H2O = how many moles?
65/18 = xx moles H2O.
moles oxygen = 1/2 moles H2O, then convert to grams oxygen.
moles H2 = same as moles H2O, convert to grmas hydrogen.
You must have
