Final answer:
The balanced chemical equation is 2NaN3(s) → 2Na(s) + 3N₂(g).
Step-by-step explanation:
The balanced chemical equation for the reaction Nan3(s) → Na(s) + N₂(g) is:
2NaN3(s) → 2Na(s) + 3N₂(g)
To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides. In this case, we have 2 sodium (Na) atoms and 6 nitrogen (N) atoms on the left side and 2 sodium (Na) atoms and 6 nitrogen (N) atoms on the right side, so the equation is balanced.
