Question

WILL Fan AND Medal!!!!!

To begin the experiment, a bomb calorimeter is filled with 1.11 g CH4 and an excess of oxygen. The heat capacity of the calorimeter, including the bomb and the water, is 4.319 kJ/g*°C . The initial temperature of the system was 24.85°C, and the final temperature was 35.65°C.

Using the formula ∆H = − m * C * ∆Τ , calculate the heat of combustion of 1.11g CH4 .

Answer 1

I think you should replace the values in the equation

Answer 2

∆H =−M ⋅ C ⋅∆T

M= 1.11 g CH4
C= 4.319 kJ /g C⋅°
∆T= T final- T initial= 35.65°C - 24.85°C = xxx °C

replace the data in the formula and calculate the ∆H

Answer 3

I did that but how do I calculate it when they are different variables

Answer 5

This question would do better under Chemistry. :)

Answer 6

I did it under there, but no one has helped me
