A bomb calorimeter can be used to mcasure the energy change of a
chemical reaction. A 0.025 sample of a
fuel is burned and found to produce
3040J of heat. Which statement is
correct?
1. The enthalpy of combustion is olki
per gram
2. The fuel must be a solid material, as
only solids can be burned in a
calorimeter
3. The enthalpy of combustion is 152 kJ
per gram
4. Thc cnthalpy of combusion is 152kJ
per molc
5. The reaction is endothermic
