SUMMARY
The discussion focuses on calculating the enthalpy change for the combustion of hydrazine (N2H4) when it reacts with oxygen to produce nitrogen gas and water. The reaction is represented as N2H4 (l) + O2 (g) → N2 (g) + 2H2O (l). The combustion of 6.50 grams of hydrazine releases 126.2 kJ of heat, leading to the need for calculating the enthalpy change per mole of hydrazine combusted. The key step involves converting the mass of hydrazine into moles to facilitate this calculation.
