Question

H2SO4 + Zn = ?H2SO4 + CuO =?HCI + CuO =? ​

Answer 1

Відповідь:

H2SO4 + Zn = ZnSO4 + H2

H2SO4 + CuO = CuSO4 + H2O

2HCI + CuO = CuCl2 + H2O

Answer 2

The balanced chemical equations for the given reactions are as follows:

1. H2SO4 + Zn → ZnSO4 + H2 This reaction between sulfuric acid (H2SO4) and zinc (Zn) produces zinc sulfate (ZnSO4) and hydrogen gas (H2).

2. H2SO4 + CuO → CuSO4 + H2O The reaction between sulfuric acid (H2SO4) and copper(II) oxide (CuO) results in the formation of copper(II) sulfate (CuSO4) and water (H2O).

3. HCl + CuO → CuCl2 + H2O When hydrochloric acid (HCl) reacts with copper(II) oxide (CuO), it forms copper(II) chloride (CuCl2) and water (H2O).
