A propellant for rockets is obtained by mixing dinitrogentetroxide N2O4 and the liquids hydrazine N2 H4. These components react to give water vapor and nitrogen gas N2, evolving 1049 kJ of heat at constant pressure when 1 mol of N2O4 reacts. Write down the balanced thermo chemical equation for this reaction. Write down the thermo chemical reaction for the above if there were only1 mol of N2O4 and also write the thermo chemical reaction for the REVERSE of the reaction described previously.
