Limiting reactant question??? please help what am I doing wrong?
So the question says NH3 + O2 --> NO + H2O
So I balanced the equation and got
4NH3+9O2 --> 6NO3 + 6H2O
I converted grams to moles and then multplied by the mole ratio
so I got 3.25 g of NH3 will produce .286259 moles of O2 (didn't say which one to use so I just picked water)
For O2 I got 3.5 grams produces .65625 moles of H2O
HOWEVER the answer says the limiting reactant is O2. How can this be if NH3 produces less water?
please explain or work out if possible
