1. You used a bomb calorimeter, or constant-volume calorimeter, but misplaced the information of heat capacity of the calorimeter. If you burn 1.250 g of an organic compound, with, ΔE = -24.30kJ/g, and measured a temperature change from 25.00oC to 47.60oC, what must the heat capacity of the calorimeter be?
2. Using the Hess's Law and the manipulations of the following thermochemical equations:
P4(s) + 6Cl2(g) -> 4PCl3(g) ΔH : -2439 kJ
P4(s) + 10Cl2(g) -> 4PCl5(g) ΔH : -3438 kJ
Determine the enthalpy oI reaction for the following reaction:
PCI5(g) -> PCI3(g) + Cl2(g) ΔH = ?
Please make answers as detailed as possible showing all steps so I can see where I'm going wrong. I thought I knew what I was doing but I'm so lost. Please help I have to turn this is in soon and have been working on it forever.
