Question

predicting the products of a decomposition reaction
if calcium carbonate (caco₃) decomposes, what would the product of the reaction be?
caco₃ → + co₂

Explanation:

Step1: Recall Decomposition of Carbonates

Calcium carbonate (\(CaCO_3\)) decomposes upon heating (or under certain conditions) into calcium oxide (\(CaO\)) and carbon dioxide (\(CO_2\)). The reaction is \(CaCO_3
ightarrow CaO + CO_2\).

Step2: Identify the Missing Product

From the given equation \(CaCO_3
ightarrow \_\_ + CO_2\), the missing product is calcium oxide (\(CaO\)).

Answer:

\(CaO\)
