Consider the raction between N 2 H 4 and N 2 O 4 : 2 N 2 H 4 ( g ) + N 2 O 4 ( g ) → 3 N 2 ( g ) + 4 H 2 O ( g ) A reaction vessel initially contains 27.5g N 2 H 4 and 74.9g of N 2 O 4 . Calculate the masses of N 2 H 4 , and H 2 O that will be in reaction vessel after the reactants have reacted as much as possible. Assume 100% yield. Hint: The limiting reactant is completely consumed, but the reactant in excess is not. Use the amount of limiting reactant to determine the amount of products that form and the amount of the reactant in excess that remains after complete reaction.
