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 0.95-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. Calculate the heat of combustion of the acetylene sample (in kJ)? Input values only in two decimal places. Include negative sign if it is negative

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 0.95-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.

Calculate the heat of combustion of the acetylene sample (in kJ)? Input values only in two decimal places. Include negative sign if it is negative.
