The enthalpy of combustion of solid carbon to form carbon dioxide is -393.7 kJ/mol carbon, and the enthalpy of combustion of carbon monoxide to form carbon dioxide is -283.3 kJ/mol CO. Use these data to calculate ΔH for the reaction 2 C(s) + O2 (g) 2 CO (g)

d: the voltage of the secondary coil is less than that of the primary coil.
