1. A scientist burns 2.65g of hydrazine (N2H4) in a calorimeter. The calorimeter contains 200g of water at an initial temperature of 20 degrees Celsius. The temperature of the water increases to 81.6 degrees Celsius. What is the molar enthalpy of combustion for hydrazine?
a. How much heat energy did the water in the calorimeter absorb? [the specific heat of water is 4.18 J/gC]
PLEASE HELP! and answer both questions please please please
