Question
Calcium carbonate (CaCO3) is a common substance found in rocks. When it's heated, it breaks down to form a new solid, calcium oxide (CaO). This reaction releases carbon dioxide gas (CO2).Determine the symbol equation for this reaction, including state symbols.Note: You can copy and paste this arrow: →
Solution
The balanced chemical equation for the reaction is:
CaCO3(s) → CaO(s) + CO2(g)
Here's the step-by-step process:
-
Write down the formulas of the reactant and the products. The reactant is calcium carbonate (CaCO3) and the products are calcium oxide (CaO) and carbon dioxide (CO2).
-
Write down the state symbols. Calcium carbonate is a solid (s), calcium oxide is a solid (s), and carbon dioxide is a gas (g).
-
Balance the equation. In this case, the equation is already balanced, meaning there's the same number of each type of atom on both sides of the equation.
So, the final balanced equation with state symbols is:
CaCO3(s) → CaO(s) + CO2(g)
