Write the reaction equation according to the scheme: iron oxide 2 (FeO2) + hydrogen (H) -iron (Fe) + water

Write the reaction equation according to the scheme: iron oxide 2 (FeO2) + hydrogen (H) -iron (Fe) + water (H2O) 2) Calcium carbonate (caco3) + Hydrochloric acid (HCl) -Calcium chloride CaCl + water (H2O) + oxide carbon4

In this task, it is necessary to write down the equations of chemical reactions according to a given scheme.

FeO + H2 = Fe + H2O.

This reaction is called a substitution reaction. In this reaction, hydrogen reacts with iron oxide to form iron and water.

CaCO3 + 2HCl = CaCl2 + H2O + CO2.

This reaction is called an exchange reaction. When calcium carbonate reacts with hydrochloric acid, the result is calcium chloride, water and carbon monoxide.
