WebStandard enthalpy of combustion is the enthalpy change when 1 mole of a substance burns (combines vigorously with oxygen) under standard state conditions; it is sometimes called “heat of combustion.” For example, the enthalpy of combustion of ethanol, −1366.8 kJ/mol, is the amount of heat produced when one mole of ethanol undergoes ... WebThe enthalpies of formation of the compounds in the combustion of methane, CH4(g) + 2O2(g) ... CO2 (g): Hf = -393.5 kJ/mol; and H2 O(g): Hf = -241.82 kJ/mol. How much … WebThe standard molar enthalpy of formation of methane is negative 74.8 kilojoules per mole. So we're multiplying one mole by negative 74.8 kilojoules per mole. Our other reactant is oxygen. And we know that diatomic oxygen gas has a standard enthalpy of formation of zero. ... For this balanced equation, we're showing the combustion of one mole of ... 4h最新地址
