Which of the proposed substances will interact with: hydrochloric acid, copper, barium hydroxide, iron, barium sulfate

Which of the proposed substances will interact with: hydrochloric acid, copper, barium hydroxide, iron, barium sulfate, zinc oxide, carbon dioxide, barium carbonate. Write down the equations of possible reactions.

HCl – Cu, Ba (OH) 2, Fe, BaSO4, ZnO, CO2, BaCO3;

1) hydrochloric acid does not interact with copper, because copper is among the activities of metals after hydrogen;

2) hydrochloric acid interacts with barium hydroxide (neutralization reaction):

2 HCl + Ba (OH) 2 = Ва Cl2 + 2 Н2О

3) hydrochloric acid interacts with iron, which is in the line of metal activity to hydrogen:

2 HCl + Fe = Fe Cl2 + H2

4) hydrochloric acid interacts with zinc oxide:

2 HCl + ZnO = Zn Cl2 + H2O

5) hydrochloric acid does not interact with carbon dioxide, because it is an acidic oxide;

6) hydrochloric acid interacts with barium carbonate, which is formed by a weaker acid:

2 HCl + BaCO3 = Ва Cl2 + Н2О + СО2
