Using tabulated thermodynamic data, calculate $\Delta \text{G}°$ for these reactions.

(a) ${\text{Mg}}_{\text{3}}{\text{N}}_{\text{2}}\left(\text{s}\right)+{\text{6H}}_{\text{2}}\text{O}(\mathcal{l})\to 2{\text{NH}}_{\text{3}}\left(\text{g}\right)+\text{3Mg}{\left(\text{OH}\right)}_{\text{2}}\left(\text{s}\right)$

(b) ${\text{4CH}}_{\text{3}}{\text{NH}}_{\text{2}}\left(\text{g}\right)+{\text{9O}}_{\text{2}}\left(\text{g}\right)\to {\text{4CO}}_{\text{2}}\left(\text{g}\right)+\text{1}0{\text{H}}_{\text{2}}\text{O}(\mathcal{l})+{\text{2N}}_{\text{2}}\left(\text{g}\right)$

(c) ${\text{Fe}}_{\text{3}}\text{O}\left(\text{s}\right)+\text{4CO}\left(\text{g}\right)\to \text{3Fe}\left(\text{s}\right)+{\text{4CO}}_{\text{2}}\left(\text{g}\right)$

(d) ${\text{P}}_{\text{4}}{\text{O}}_{\text{1}0}\left(\text{s}\right)+{\text{6H}}_{\text{2}}\text{O}\left(\mathcal{l}\right)\to {\text{4H}}_{\text{3}}{\text{PO}}_{\text{4}}\left(\text{aq}\right)$
