Make up the equations for the reactions of aluminum, iron, copper oxide, zinc oxide with acid: a) hydrochloric, b) sulfuric (solution).

1.) First, we write down the chemical equation for the reaction of aluminum with hydrochloric acid.
2Al + 6HCl = 2AlCl₃ + 3H₂.
As a result of this reaction, aluminum chloride AlCl₃ and hydrogen H₂ are formed.
2.) Now we write down the equation for the reaction of iron with hydrochloric acid.
2Fe + 6HCl = 2FeCl₃ + 3H₂.
As a result of this reaction, ferric chloride FeCl₃ and hydrogen H₂ are formed.
3.) Let us write the chemical equation for the reaction of copper oxide with hydrochloric acid.
CuO + 2HCl = CuCl₂ + H₂O.
As a result of this reaction, copper chloride CuCl₂ and water H₂O are formed.
4.) Now we write down the chemical equation for the reaction of zinc oxide with hydrochloric acid.
2HCl + ZnO = ZnCl₂ + H₂O.
As a result of this reaction, zinc chloride ZnCl₂ and water are formed.
5.) Next, we write down the equation for the reaction of aluminum with a sulfuric acid solution.
2Al + 3H₂SO₄ = Al₂ (SO₄) ₃ + 3H₂.
As a result of this reaction, aluminum sulfate Al₂SO₄ and hydrogen H₂ are formed.
6.) Let’s compose the equation for the reaction of iron with a solution of sulfuric acid.
2Fe + H₂SO₄ = Fe₂ (SO₄) ₃ + 3H₂.
As a result of this reaction, iron sulfate Fe₂SO₄ and hydrogen H₂ are formed.
7.) Now we write down the equation for the reaction of copper oxide with sulfuric acid solution.
CuO + H₂SO₄ = CuSO₄ + H₂O.
As a result of this reaction, copper sulfate CuSO₄ and hydrogen H₂ are formed.
8.) Now we write down the equation for the reaction of zinc oxide with sulfuric acid solution.
ZnO + H₂SO₄ = ZnSO₄ + H₂O.
As a result of this reaction, zinc sulfate or zinc sulfate ZnSO₄ is formed, as well as water H₂O.
9.) Let’s write the equation of the reaction of nitric acid with sodium oxide.
2HNO₃ + Na₂O = 2NaNO₃ + H₂O.
As a result of this reaction, sodium nitrate or sodium nitrate NaNO₃ is formed, as well as water.
