Question

А)Cu→CuO→CuCl₂→Cuб)Zn→ZnCl₂→Zn(OH)→ZnO

Answer 1

а)Cu→CuO→CuCl₂→Cu
1)2Cu+O²⇒2CuO
2)CuO+2HCl⇒CUCl²+H2O
3)CuCl²⇒CU+Cl²
б)Zn→ZnCl₂→Zn(OH)→ZnO
1)Zn+Cl²⇒ZnCl²
2)ZnCl+H2O⇒Zn(OH)+HCl
3)Zn(OH)⇒ZnO+H2O

Answer 2

It looks like you're describing two different chemical reactions involving copper (Cu) and zinc (Zn). Let me break down each of these reactions for you:

A) Copper (Cu) Reaction:

1. Cu → CuO (Copper Oxide): Copper (Cu) reacts with oxygen in the air to form copper oxide (CuO).

2. CuO → CuCl₂ (Copper Chloride): Copper oxide (CuO) reacts with hydrochloric acid (HCl) to form copper chloride (CuCl₂) and water (H2O).

B) Zinc (Zn) Reaction:

1. Zn → ZnCl₂ (Zinc Chloride): Zinc (Zn) reacts with hydrochloric acid (HCl) to form zinc chloride (ZnCl₂) and hydrogen gas (H2).

2. ZnCl₂ → Zn(OH)₂ (Zinc Hydroxide): Zinc chloride (ZnCl₂) reacts with sodium hydroxide (NaOH) to form zinc hydroxide (Zn(OH)₂) and sodium chloride (NaCl).

3. Zn(OH)₂ → ZnO (Zinc Oxide): Zinc hydroxide (Zn(OH)₂) can be dehydrated or heated to form zinc oxide (ZnO).

Please note that these reactions represent simplified chemical transformations, and the actual reaction conditions and products may vary depending on factors such as concentration, temperature, and other reactants involved. It's important to use proper safety precautions when working with chemicals.
