Problem: A 1.800-g sample of solid phenol (C6H5OH(s)) was burned in a bomb calorimeter, which has a total heat capacity of 11.66 kJ/oC. The temperature of the calorimeter plus its contents increased from 21.36oC to 26.37oC.Write a balanced chemical equation for the reaction that takes place in the bomb calorimeter.

Combustion reaction → takes place in a bomb calorimeter

  • produces CO2 and H2O


Complete reaction: C6H5OH(s) + O(g) → CO2 (g) + H2O (l)


To balance a chemical equation → number of atoms of each element must be the same for both sides of the equation

  • add a coefficient
