For combustion of ethane in air to form carbon dioxide and water, the system includes all the reactants and products Enthalpy, internal energy, temperature, and pressure are state functions because they all depend only on the initial and final states of the system Work (w) is positive when work is done on the system by the surroundings Melting of ice is an endothermic process O_2(g) and O(g) have the same The standard enthalpy of formation of Cu(s) is 0 kJ/mol. The standard enthalpy of formation of Fe(g) is 0 kJ/mol. Consider the reaction Is the reaction endothermic or exothermic? Which has the higher enthalpy under these conditions, the product, Ca(OH)_2(aq), or the reactants, CaO(s) + H_2O(1)?
