$D$. for either thermal combination redox reaction or thermal decomposition redox reaction.

Vedclass · Answer

(D) In the reaction $3Mg_{(s)} + N_{2(g)} \longrightarrow Mg_3N_{2(s)}$,the oxidation state of $Mg$ changes from $0$ to $+2$ (oxidation) and the oxidation state of $N$ changes from $0$ to $-3$ (reduction).Since two different elements are undergoing oxidation and reduction,it is an intermolecular redox reaction.Furthermore,this is a combination reaction where two elements combine to form a single compound.Therefore,it fits the category $D$ for thermal combination redox reaction.

Assign $A, B, C, D$ from the given type of reaction.
$3Mg_{(s)} + N_{2(g)} \longrightarrow Mg_3N_{2(s)}$
