The decomposition of solid barium nitrate leads to the formation of solid barium oxide, diatomic nitrogen gas, and diatomic oxygen gas. Write a formula equation for the reaction.

Ba(NO₃)₂(s) ⇒ BaO(s) + N₂(g) + 3 O₂(g)

Explanation:

Let's consider the unbalanced equation for the decomposition reaction of solid barium nitrate.

Ba(NO₃)₂(s) ⇒ BaO(s) + N₂(g) + O₂(g)

We can see that Ba atoms and N atoms are balanced, but we have 6 O atoms to the left side and 2 O atoms to the right. We can get the balanced equation by multiplying O₂(g) by 3.

Ba(NO₃)₂(s) ⇒ BaO(s) + N₂(g) + 3 O₂(g)
