"Water gas" is an industrial fuel composed of a mixture of carbon monoxide and hydrogen gases. When this fuel is burned, carbon dioxide and water result. From the information given below, write a balanced equation and determine the enthalpy of this reaction: CO(g) + O2(g) → CO₂(g) + 282.8 kJ H2(g) + O2(g) → H₂O(g) + 241.8 kJ MacBook Air
