Write the reaction of interaction between substances c) Zn with H2so4; Al with HCl d) Zn with CuSO4; Al c NaOH; Be with KOH

Zinc react with sulfuric acid, resulting in the formation of zinc sulfate, hydrogen sulfide and water.

4 Zn + 5 H2SO4 = 4 ZnSO4 + H2S + 4 H2O

The reaction between aluminum and hydrochloric acid, as a result of the reaction, aluminum chloride is formed and hydrogen is released.

2 Al + 6 HCl = 2 AlCl3 + 3 H2

Zinc react with copper sulfate, resulting in the formation of zinc sulfate and pure copper. The reaction proceeds according to the type of substitution.

Zn + CuSO4 = ZnSO4 + Cu

The reaction between aluminum and sodium hydroxide, as a result of the reaction, sodium oxide is formed, oxygen is released and a substance such as sodium aluminate is formed.

2 Al + 6 NaOH = 2 NaAlO2 + 3 H2 + 2 Na2O

Beryllium potassium hydroxide react with water. As a result of the reaction, bivalent potassium tetrahydroxozincate is formed and hydrogen is released.

Be + KOH + H2O = K2 [Be (OH) 4] + H2.
