Question

Take the reaction: NH3 + O2 ---> NO + H2O. In an experiment, 3.25 g of NH3 are allowed to react with 3.50 g of O2.  Which reactant is the limiting reagent?
You may either write the formula or the name of the limiting reactant.

I do these the long way.
1. Balance the equation.
2. Convert g NH3 to mols. mols = grams/molar mass = ?
3. Convert g O2 to mols.
4. Using the coefficients in the balanced equation, convert mols NH3 5o mols NO.
5. Do the same and convert mols O2 to mols NO.
6. It is quite likely that these two values for mols NO produced will not be the same which means one of them is wrong. The correct value in limiting reagent problems is ALWAYS the smaller value.
