Answer» The reaction of cyanamide, $N H_{2} C N (s)$ with oxygen was run in a bomb calorimeter and $Δ U$ was found to be $- 742.24 k J m o l^{- 1}$ .The magnitude of $Δ H_{298}$ for the reaction $N H_{2} C N (s) + \frac{3}{2} (g) \to N_{2} (g) + C O_{2} (g) + H_{2} O (l)$ is ______ kJ. (Rounded off to the nearest integer) [Assume ideal gases and $R = 8.314 J m o l^{- 1} K^{- 1}$ ]
