When an acid reacts with a metal carbonate, the products are a salt, water, and carbon dioxide gas. Step 1: Identify the general reactants. Acid + Metal Carbonate Step 2: Determine the general products. The acid donates H^+ ions, and the carbonate ion (CO_3^2-) reacts to form water (H_2O) and carbon dioxide (CO_2). The metal cation from the carbonate combines with the anion from the acid to form a salt. Step 3: Write the general reaction. Acid + Metal Carbonate → Salt + Water + Carbon Dioxide For example, if hydrochloric acid (HCl) reacts with calcium carbonate (CaCO_3): 2HCl (aq) + CaCO_3 (s) → CaCl_2 (aq) + H_2O (l) + CO_2 (g) That's 2 down. 3 left today — send the next one.
