You are quite right. The heating value of coal varies with type, from 15,000 to 27,000 kJ/kg for soft coals, reaching 31,000 for coke and 34,000 for anthracite. They may want you to use the heat of formation of Carbon (graphite). It is a poorly constructed question.
The balanced reaction is
C + O2 -> CO2
Calculate the standard cahnge in enthalpy for the combusation of coal/ Show the balnaced reaction. How does one get the balanced reaction of coal? Coal has many substances that make up its compsistion
