Sorry that is Incorrect
The correct answer is: Salt, carbon dioxide and water. All of the other answers are incorrect. Here is why:
- Hydrogen gas and salt--> These are the products of an acid reaction with a chloride, not a carbonate reaction.
- Salt and water--> These are the products of an acid reaction with a base, not a carbonate.
- Salt, carbon dioxide and water--> This is correct
- Salt and carbon dioxide --> These are not the products of any acid reaction.
