I) Using standard enthalpy of formation values from the appendix in your textbook, calculate the enthalpy of combustion, Delta H^circ comb, of one mole of ethane at 25^circ C C_(2)H_(6)(g)+3.5O_(2)(g)arrow 2CO_(2)(g)+3H_(2)O(l)

To calculate the enthalpy of combustion, comb, of one mole of ethane, we need to use the standard enthalpy of formation values for the reactants and products in the given chemical equation.The balanced chemical equation for the combustion of ethane is: The standard enthalpy of formation values for the reactants and products are: : : (since it is the standard state) : : Now, we can calculate the enthalpy of combustion using the formula: Substituting the values, we get: Therefore, the enthalpy of combustion, comb, of one mole of ethane at is .
