What is the similarity in the reaction of carbonates and hydrogen carbonates with acids?

Answer and explanation

Correct answer: Both form carbon dioxide, water, and salt

The governing reaction pattern is acid plus carbonate or hydrogencarbonate producing a salt, water, and carbon dioxide. For example, an acid reacting with a carbonate releases CO2, while an acid reacting with a hydrogencarbonate also releases CO2 after the intermediate carbonic acid decomposes. Thus option A correctly states the common products. The other options omit the characteristic gas or name products that are not formed.
