Chapter 12, Problem 142AE

Using data from this chapter, calculate the change inenergy expected for each of the following processes.
a. $\text{Na(}g\text{)+Cl(}g\text{)}\to {\text{Na}}^{\text{+}}\text{(}g{\text{)+Cl}}^{\text{–}}\text{(}g\text{)}$
b. $\text{Mg(}g\text{)+F(}g\text{)}\to {\text{Mg}}^{\text{+}}\text{(}g{\text{)+F}}^{\text{–}}\text{(}g\text{)}$
c. ${\text{Mg}}^{\text{+}}\text{(}g\text{)+F(}g\text{)}\to {\text{Mg}}^{\text{2+}}\text{(}g{\text{)+F}}^{\text{–}}\text{(}g\text{)}$
d. $\text{Mg(}g\text{)+2F(}g\text{)}\to {\text{Mg}}^{\text{2+}}\text{(}g{\text{)+2F}}^{\text{–}}\text{(}g\text{)}$
