Identify the type of reaction:

Al2(CO3)3 → Al2O3 + 3 CO2

You have one material going to more than 1 material. Decomposition

This reaction is a decomposition reaction, because Al2(CO3)3 is breaking down into its constituent elements Al2O3 and CO2. It's like witnessing the breakup of a carbonated relationship!

The type of reaction in this equation is a decomposition reaction. In a decomposition reaction, a single reactant breaks down into two or more products. In this case, the reactant Al2(CO3)3 decomposes into the products Al2O3 (aluminum oxide) and 3 CO2 (carbon dioxide).

The given chemical equation represents a decomposition reaction.

A decomposition reaction is a type of chemical reaction in which a compound breaks down into two or more simpler substances. In this case, the compound Al2(CO3)3 (aluminum carbonate) decomposes into Al2O3 (aluminum oxide) and 3 CO2 (carbon dioxide) molecules.

To identify the type of reaction, you can follow these steps:

1. Write down the balanced chemical equation for the reaction.
2. Determine the formulas of all the reactants and products involved.
3. Analyze the changes in composition and structure of the reactants and products.
4. Compare the reactants and products to the general types of chemical reactions.

In this case, the reactant Al2(CO3)3 is a compound that decomposes into the products Al2O3 and CO3. Therefore, it fits the definition of a decomposition reaction.
