Heat transfer from the chamber to the surroundings

Discuss the below problem:

Q: In a test of rocket propellant performance, liquid hydrazine (N2H4) at 100 kPa, 25°C, and oxygen gas at 100 kPa, 25°C, are fed to a combustion chamber in the ratio of 0.5 kg O₂/kg N2H4. The heat transfer from the chamber to the surroundings is estimated to be 100 kJ/ kg N₂H₄, determine the temperature of the products exiting the chamber. Assume that only H₂O, H₂, and N₂are present. The enthalpy of formation of liquid hydrazine is -50417 kJ/kmol.
