Calculate the standard enthalpy change for the reaction in which 6 moles of calcium oxide reacts with 3 moles of carbon dioxide to produce 2 moles of calcium carbonate. The equation for the reaction is:CaO(s) + CO2(g) → CaCO3(s)Given the standard enthalpy of formation values: ΔHf°[CaO(s)] = -635.09 kJ/mol, ΔHf°[CO2(g)] = -393.51 kJ/mol, and ΔHf°[CaCO3(s)] = -1207.44 kJ/mol.

Calculate the corrosion potential of a copper electrode immersed in a 1 M CuSO4 solution in contact with a silver electrode immersed in a 1 M AgNO3 solution. Given that the standard reduction potentials of Cu2+/Cu and Ag+/Ag are +0.34 V and +0.80 V, respectively. Determine which electrode will corrode and which electrode will act as a cathode in the galvanic cell.
