1. First, you need to understand what a thermal decomposition reaction is. It is a type of reaction where a substance breaks down into two or more substances when it is heated.

2. In the case of a metal carbonate, the general formula for its thermal decomposition is:
MCO3 → MO + CO2
where M represents the metal.

3. To determine if a metal carbonate has undergone a thermal decomposition reaction, you would need to look for evidence of the products of the reaction.

4. One of the products is a metal oxide (MO). This may be visible as a new solid substance that was not present before the reaction.

5. The other product is carbon dioxide (CO2). This is a gas, so you would look for evidence of gas being produced. This could be bubbling, effervescence, or the gas could be captured and tested.

6. One common test for carbon dioxide is to bubble the gas through limewater. If the limewater turns cloudy, then carbon dioxide is present.

7. Therefore, if you see a new solid substance and evidence of carbon dioxide gas, then it is likely that the metal carbonate has undergone a thermal decomposition reaction.
