Question

what is the missing coefficient to make a balanced equation? ?n₂ + k → k₃n be sure the equation is balanced before entering the coefficients. 4 6 2 1

Explanation:

Step1: Balance nitrogen atoms

We have 2 nitrogen atoms in $N_2$ on the left - hand side. In $K_3N$ on the right - hand side, there is 1 nitrogen atom. To balance nitrogen, the coefficient of $K_3N$ must be 2 so that we have 2 nitrogen atoms on both sides: $N_2+K
ightarrow2K_3N$.

Step2: Balance potassium atoms

On the right - hand side, in $2K_3N$, we have 6 potassium atoms. So the coefficient of $K$ on the left - hand side must be 6. The balanced equation is $N_2 + 6K
ightarrow2K_3N$.
