Some rocket engines use a mixture of hydrazine, N2H4 and hydrogen peroxide, H2O2 as the propellant. The reaction is given by the following equation. N2H2(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 |
