Question

Напишите уравнения реакций следующих превращений ZnSO4 → Zn(OH)2 → ZnO → ZnSO4 → ZnCl2

Answer 1

Ответ:

Объяснение:

ZnSO₄ + 2KOH = Zn(OH)₂↓ + K₂SO₄

Zn(OH)₂ (t)= ZnO + H₂O

ZnO + H₂SO₄ = ZnSO₄ + H₂O

ZnSO₄ + CaCl₂ = ZnCl₂ + CaSO₄↓

Answer 2

Equations for the given transformations:

1. ZnSO4 → Zn(OH)2: - The reaction equation for the transformation of ZnSO4 to Zn(OH)2 is: ``` ZnSO4 + 2NaOH → Zn(OH)2 + Na2SO4 ``` [[9]](https://rep.vsu.by/bitstream/123456789/1980/5/%D0%9E%D0%B1%D1%89%D0%B0%D1%8F%20%D0%B8%20%D0%BD%D0%B5%D0%BE%D1%80%D0%B3%D0%B0%D0%BD%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F%20%D1%85%D0%B8%D0%BC%D0%B8%D1%8F.pdf)
