Answer 2

Metals Reacting with Hydrochloric Acid

a) Mg The reaction of magnesium with hydrochloric acid produces magnesium chloride and hydrogen gas. The balanced chemical equation for this reaction is: ``` Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) ```

b) Al Aluminum also reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. The balanced chemical equation for this reaction is: ``` 2Al(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2(g) ```

c) Ag Silver does not react with hydrochloric acid under normal conditions. This is because silver is a noble metal and is relatively unreactive with most acids, including hydrochloric acid.

d) Hg Mercury does not react with hydrochloric acid under normal conditions. This is because mercury is a noble metal and is relatively unreactive with most acids, including hydrochloric acid.

e) Ca Calcium reacts with hydrochloric acid to produce calcium chloride and hydrogen gas. The balanced chemical equation for this reaction is: ``` Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g) ```
