This is not a balanced equation. The balanced equation should be:
2BaCrO4 = 2BaO + Cr2O3 + O2
This balanced equation shows that two molecules of barium chromate (BaCrO4) decompose to form two molecules of barium oxide (BaO), one molecule of chromium(III) oxide (Cr2O3), and one molecule of oxygen gas (O2).
