In a bomb calorimeter compartment surrounded by 1.217 kg of water, the combustion of 1.023 g of benzene, C6H6 (l), raised the temperature of the water from 23.640°C to 32.692°C. The heat capacity of the calorimeter is 0.953 kJ/°C. What is ∆E for the reaction in kJ/mol of C6H6 (l), the specific heat of water is 4.184 J/g°C. Enter the correct sign (+ or -). Enter to 0 decimal places.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
