How do you balance Al N2 AIN?

Answer 1

To balance the reaction between aluminum (Al) and nitrogen (N₂) to form aluminum nitride (AlN), you start with the unbalanced equation: ( \text{Al} + \text{N}_2 \rightarrow \text{AlN} ). Since each formula unit of AlN requires one aluminum atom and one nitrogen atom, and nitrogen is diatomic, you need two moles of aluminum for every mole of N₂. The balanced equation is ( 6 \text{Al} + \text{N}_2 \rightarrow 2 \text{Al}_3\text{N}_2 ), ensuring that both sides have equal numbers of each type of atom.
