Write the equation for the reaction of an acid with the following substances: 1) Fe 2) FeO 3) Fe (OH) 2 4) FeCo3 5) Co2

1) 2HCl + Fe -> FeCl2 + H2 substitution reaction

2) 2HCl + FeO -> FeCl2 + H2O exchange reaction

3) 2HCl + Fe (OH) 2 -> FeCl2 + 2H2O exchange reaction

4) 2НCl + FeCO3 -> FeCl2 + CO2 + H2O such reactions of acids with salts are possible only if one of the products precipitates or is released as a gas (in this case, carbon dioxide is released)

5) 4HCl + CO2 -> CCl4 + 2H2O
