Calculation of standard enthalpy change for the combustion of propane.If 5 moles of propane react completely in a bomb calorimeter under standard conditions, calculate the standard enthalpy change for the combustion of propane. The balanced chemical equation for the combustion of propane is:C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g) Given the standard enthalpy of formation at 25°C and 1 atm for C3H8(g), CO2(g), H2O(g) are -103.8 kJ/mol, -393.5 kJ/mol and -241.8 kJ/mol respectively.

Calculate the exchange current density for a Zinc electrode immersed in a solution containing 0.1 M Zinc ions at 25 degrees Celsius, given that the standard potential of the Zinc half-reaction is -0.76 V and the transfer coefficient is 0.5. (Assume concentration polarization effects to be negligible.)
