Interpretation:
Reaction that provides more heat has to be identified.
Answer to Problem 90QRT
The heat evolved from one gram of 1,1-dimethylhydrazine is more than enthalpy evolved from one gram of hydrazine.
Explanation of Solution
The given equations for combustion are as follows,
The combustion enthalpy value is as follows,
The enthalpy evolved for one gram of the two given substances are calculated as shown below,
From above calculations it is clear that enthalpy evolved from one gram of 1,1-dimethylhydrazine is more than enthalpy evolved from one gram of hydrazine.
