The energy transferred as heat in kilojoules when 70 lb of coal is burned should be calculated. Concept introduction: Enthalpy of combustion is the energy released by a combustion reaction between hydrocarbons, oxygen and heat source. Enthalpy of formation is the heat released or absorbed in a chemical reaction at constant temperature when simple substances combine into a more complex substance. 1 lb = 453 .6 g
