Acetylene, C2H2 , is used in welding torches. It releases a lot of energy when burned in oxygen. The combustion of one gram of acetylene releases 48.2 kJ. A 0.750-gram sample of acetylene is burned in a bomb calorimeter (heat capacity = 1.117kJ/OC) that contains 800.0 g of water. The final temperature of the bomb and water after combustion is 35.2OC. What is the initial temperature of the bomb and water?

Question
Acetylene, C2H2
, is used in welding torches. It
releases a lot of energy when burned in oxygen.
The combustion of one gram of acetylene releases
48.2 kJ. A 0.750-gram sample of acetylene is
burned in a bomb calorimeter (heat capacity =
1.117kJ/OC) that contains 800.0 g of water. The
final temperature of the bomb and water after
combustion is 35.2OC. What is the initial
temperature of the bomb and water?
