Which of the following is not a product of the reaction between a metal carbonate and an acid? A) Water. B) A metal oxide. C) A metal salt. Or D) Carbon dioxide.

Carbonate is a polyatomic anion with a chemical formula CO₃²⁻. This means that a metal carbonate is a compound that contains both the metal and the carbonate anion. Some examples of metal carbonates are CaCO₃ or calcium carbonate and Na₂CO₃ or sodium carbonate. An example of a carbonate you might have at home is baking soda or sodium hydrogen carbonate which has the chemical formula NaHCO₃.

When a metal carbonate such as CaCO₃ reacts with an acid such as HCL, the products of the reaction are a metal salt, in this case, CaCl₂, water, and carbon dioxide. This means that answer choice B, a metal oxide, is the correct answer choice as A, water C, a metal salt, and D, carbon dioxide, are all products of the reaction between a metal carbonate and an acid.
