Question

ZnO-Zn-Zn(NO3)2-Zn(OH)2-Na2(Zn(OH)4) помагите пожалуйста

Answer 1

ZnO→ Zn→ Zn(NO3)2→ Zn(OH)2→ Na2(Zn(OH)4)

2ZnO = 2Zn + O 2

4Zn + 10 HNO3 = 4 Zn(NO3)2 + N2O ↑+ 5H2O

Zn(NO3)2 + 2NaOH → Zn(OH)2 + 2NaNO3

Answer 2

Chemical Reactions Involving ZnO, Zn, Zn(NO3)2, Zn(OH)2, and Na2(Zn(OH)4)

When ZnO reacts with NaOH and H2O, it forms Na2[Zn(OH)4]. This reaction can be represented as:

ZnO + 2NaOH + H2O → Na2[Zn(OH)4] [[1]](https://vk.com/wall-48036687_13668)

Zinc (Zn) can form various compounds with different oxidation states. For example, Zn can have oxidation states of +1 and +2. When Zn reacts with nitric acid (HNO3), it forms Zn(NO3)2. The reaction is as follows:

Zn + 2HNO3 → Zn(NO3)2 + H2 Zinc hydroxide (Zn(OH)2) is a compound formed when zinc reacts with a base like NaOH. The reaction is as follows:

Zn + 2NaOH → Na2[Zn(OH)4] + H2O The compound Na2(Zn(OH)4) can also be formed by the reaction of ZnO with H2O and NaOH:

ZnO + 2NaOH + H2O → Na2[Zn(OH)4] [[1]](https://vk.com/wall-48036687_13668)

These reactions demonstrate the versatility of zinc in forming different compounds under various conditions.
