-3112 kJ of heat will be released when 5 moles of nitrogen is produced.

Explanation:

We are given:

Moles of nitrogen = 5 moles

Given chemical reaction follows:

$N_2H_4+O_2\rightarrow N_2+2H_2O;\Delta H=-622.4 KJ$

By stoichiometry of the reaction:

If 1 mole of nitrogen gas is produced, the heat released is -622.4 kJ

So, if 5 moles of nitrogen gas is produced, the heat released will be = $\frac{-622.4kJ}{1mol}\times 5mol=-3112kJ$

Hence, -3112 kJ of heat will be released when 5 moles of nitrogen is produced.
