Acids react with carbonates to produce the gas
A)hydrogen.
B)carbon dioxide.
C)nitrogen.
D)oxygen.

Question

Quizplus · Accepted Answer

When acids react with carbonates, they produce carbon dioxide gas. This is because carbonates are compounds that contain the carbonate ion (CO3^2-) which can release carbon dioxide gas when reacted with an acid. The hydrogen ion (H+) from the acid reacts with the carbonate ion to produce carbon dioxide (CO2), water (H2O), and a salt (an ionic compound). Therefore, the correct choice is B - carbon dioxide.
