Some rocket engines use a mixture of hydrazine, N2H4 and hydrogen peroxide, H2O2 as the propellant. The reaction is given by the following equation.

N22(l)+2H2O2(l)→N2(g)+4H2O(g)

How much of the excess reactant, remains unchanged when 0.750mol of N2H4 is mixed with 17g of H2O2?

(a)

16g N2H4

(b)

0.25mol H2O2

(c)

0.25mol N­2H4

(d)

8.5g H2O2
