Write balanced chemical equations, including states, for the following reactions: Magnesium hydrogen carbonate solution reacts with hydrochloric acid to produce magnesium chloride solution, carbon dioxide gas and water.

MgCO 3 (s)+2HCl(aq)→MgCl 2 (aq)+CO2 (g)+H2 O(l)

Explanation:

MgCO 3 (s)+2HCl(aq)→MgCl 2 (aq)+CO2 (g)+H2 O(l)

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
