Answer 1

Ответ:

Объяснение:

ZnSO4+BaCl2 → ZnCl2+BaSO4

ZnCl2+2KOH→Zn(OH)2+2KCl

Zn(OH)2+2HNO3→Zn(NO3)2+2H2O

Answer 2

The sequence of chemical reactions you've provided involves the transformation of zinc sulfate (ZnSO4) into zinc nitrate (Zn(NO3)2) through a series of intermediate reactions. Let's break down each step in the sequence:

1. ZnSO4 (Zinc Sulfate) → ZnCl2 (Zinc Chloride):

   • To convert zinc sulfate into zinc chloride, you can add hydrochloric acid (HCl) to zinc sulfate. The chemical reaction is as follows: ZnSO4 + 2HCl → ZnCl2 + H2SO4

2. ZnCl2 (Zinc Chloride) → Zn(OH)2 (Zinc Hydroxide):

   • To convert zinc chloride into zinc hydroxide, you can add sodium hydroxide (NaOH) solution (a base) to zinc chloride. This will result in the formation of zinc hydroxide as a white precipitate: ZnCl2 + 2NaOH → Zn(OH)2 + 2NaCl

3. Zn(OH)2 (Zinc Hydroxide) → Zn(NO3)2 (Zinc Nitrate):

   • To convert zinc hydroxide into zinc nitrate, you can dissolve zinc hydroxide in nitric acid (HNO3). This will produce zinc nitrate and water: Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O

So, by following these three chemical reactions in sequence, you can transform zinc sulfate into zinc nitrate.
