When magnesium (Mg) reacts with chlorine (Cl) to form MgCl2, each atom of magnesium (gains, loses) (1,2,3,4) electron (s). As a result, each magnesium ion has a (1+,2+.3+,4+,1-,2-,3-.4-) charge.

The standard enthalpy change for the reaction of SO3 (g) with H2O (l) to yield H2SO4 (aq) is ΔH∘ = - 227.8 kJ. Use the following information S (s) + O2 (g) →SO2 (g), ΔH∘ = - 296.8kJ SO2 (g) + 12O2 (g) →SO3 (g), ΔH∘ = - 98.
