You are correct! Sodium chlorate (NaClO₃) decomposes into sodium chloride (NaCl) and oxygen gas (O₂). This is a chemical reaction, and it's important to understand the balanced equation:

2 NaClO₃ → 2 NaCl + 3 O₂

Here's what this equation tells us:

* 2 molecules of sodium chlorate (NaClO₃) react.

* This produces 2 molecules of sodium chloride (NaCl).

* It also generates 3 molecules of oxygen gas (O₂).

This reaction requires heat and is an example of a decomposition reaction.
