If solid S is heated strongly, gas G is produced. G causes limewater to become cloudy. Name S and G and state the type of reaction that S undergoes.
- AS: calcium carbonate, G: carbon dioxide, type of reaction: combustion
- BS: calcium carbonate, G: carbon dioxide, type of reaction: thermal decomposition
- CS: sodium carbonate, G: oxygen, type of reaction: combustion
- DS: sodium carbonate, G: oxygen, type of reaction: thermal decomposition
