Answer
The products are: $CO_2(g)$ and $BaO(s)$
Balanced equation:
$BaCO_3(s) --\gt CO_2(g) + BaO(s)$
Work Step by Step
1. In a decomposition reaction, the reactants splits into two or more simple compounds/elements.
Compounds with "$CO_3$" tend to form $CO_2$ and the oxide of the other element.
Therefore, the products probably are: $CO_2(g)$ and $BaO(s)$
$BaCO_3(s) --\gt CO_2(g) + BaO(s)$
- The equation is already balanced.
