Why is standard enthalpy of formation of hydrogen zero?
WebbWe have two moles of H2O. And the standard enthalpy of formation of H2O is negative 285.8. So we're gonna multiply this by negative 285.8 kilojoules per mole. So moles … WebbThe standard enthalpy of formation of H2O (l) is -286 kJ/mol and the standard enthalpy of combustion of ethane is -1560 kJ/mol. What has a standard enthalpy of formation equal to zero?
