Question

To begin the experiment, 1.11g of methane CH4is burned in a bomb calorimeter containing 1000 grams of water. The initial temperature of water is 24.85oC. The specific heat of water is 4.184 J/g oC. The heat capacity of the calorimeter is 695 J/ oC . After the reaction the final temperature of the water is 35.65oC.

Using the formula qwater =m•c•ΔT ,calculate the heat absorbed by the water

Using the formula qcal = Ccal •ΔT,calculate the heat absorbed by the calorimeter.

Answer 1

1. CH4 + 2O2 → CO2 + 2H2O
2. 10.80 degrees celsius
3. 45,187 J
4. 7,506 J
5. 52,693 J
