B) $2 \mathrm { Al } ( \mathrm { s } ) + \mathrm { N } _ { 2 } ( \mathrm {~g} ) \stackrel { \Delta } { \rightarrow } 2 \mathrm { AlN } ( \mathrm { s } )$
C) $2 \mathrm { Al } ( \mathrm { s } ) + 2 \mathrm {~N} ( \mathrm {~g} ) \stackrel { \Delta } { \rightarrow } 2 \mathrm { AlN } ( \mathrm { s } )$
D) $2 \mathrm { Al } ( \mathrm { s } ) + \mathrm { N } _ { 2 } ( \mathrm {~g} ) \stackrel { \mathrm { A } } { \rightarrow } \mathrm { Al } _ { 2 } \mathrm {~N} _ { 2 } ( \mathrm {~s} )$
E) $\mathrm { Al } _ { 2 } ( \mathrm {~s} ) + \mathrm { N } _ { 2 } ( \mathrm {~g} ) \stackrel { \Delta } { \rightarrow } 2 \mathrm { AlN } ( \mathrm { s } )$
