Question

Metal carbonate reacts with hydrobromic acid to release____?

Answer 1

Answer:

Co2

Explanation:

Answer 2

Carbon dioxide.

Explanation:

Acids react with metal carbonates to form corresponding salts, carbon dioxide and water.

Metal carbonate reacts with hydrobromic acid to release carbon dioxide.

Hydrobromic acid on reaction with sodium carbonate forms sodium bromide, carbon dioxide and water.

 2HBr  + Na2​CO3 ​⟶ 2NaBr (s) + CO2​ (g) + H2​O (l)

Carbon dioxide is released as gas, while NaBr is a precipitate and water is aqueous.
