Answer to Question #219973 in General Chemistry for jmnt

Question

Acetylene, C2H2, is a gas used in welding. The molar enthalpy of combustion for acetylene is -2599 kJ. A mass of 0.338 g C2H2(g) is combusted in a bomb calorimeter. Ifthe heat capacity of the calorimeter is 5.54 kJ/°C, what is the temperature increase ofthe bomb calorimeter?

Answer 1

ΔH = CpΔT =

-2599= (0.338 g)(5.54 J/g-°C)(X)

= 6.09°C
