If you know that H2O2 is the limiting reactant, you know that after the reaction, none remains. All the H2O2 needed to react with the excess reactant, N2H4 in its propper molar ratios. ... For concentration problems u must know the almighty formulae: No. of moles= Concentration x Volume (when the volume is given in L or dm^3);

a. The stoichiometric ratio is given by using the coefficients of the balanced equation. The coefficients are the numbers listed before each formula. This equation is already balanced, so refer to the tutorial ... The 'insufficient' component (H2) is the limiting reactant. Another way to put it is to say that O2 is in excess.

Limiting reagent - Wikipedia, the free encyclopedia
In chemistry, the limiting reagent , also known as the " limiting reactant ", is the chemical that determines how far the reaction will go before the chemical in question gets "used up", causing t...
