With which of the listed substances does hydrochloric acid react: zinc oxide, carbon monoxide 4, iron, copper?

With which of the listed substances does hydrochloric acid react: zinc oxide, carbon monoxide 4, iron, copper? Draw up the equations of possible reactions in molecular and ionic form.

In this task, it is necessary to determine with which compounds hydrochloric acid reacts.

1. Reaction with zinc oxide.

ZnO + 2HCL = ZnCl2 + H2.

We write down the reaction in ionic form.

2H + + O2- = H2O.

When zinc oxide reacts with hydrochloric acid, zinc chloride and hydrogen are formed as a result.

2. Reaction with carbon monoxide.

This reaction does not proceed because the acid does not react with the acidic oxide.

3. Reaction with iron.

2HCl + Fe = FeCl2 + H2.

We write it in ionic form.

2H + + Fe0 = Fe2 + + H2.

The result is ferric chloride and hydrogen.

4. Reaction with copper.

This reaction does not proceed.
