2) Гидроксосульфат алюминия
3) гидросульфид кадмия
4) дигидроортофосфат кальция
5)Нитрат алюминия

Answer 2

Salts:

1. [Fe(OH)2]2CrO4: This compound is called iron(II) chromate. It is formed by the reaction between iron(II) hydroxide and chromic acid. The balanced chemical equation for this reaction is:

3Fe(OH)2 + 2H2CrO4 → [Fe(OH)2]2CrO4 + 4H2O.

2. AlOHSo4: The given formula seems to be incorrect. However, if we assume that it is aluminum hydroxide sulfate, the correct formula would be Al(OH)2SO4. This compound is formed by the reaction between aluminum hydroxide and sulfuric acid. The balanced chemical equation for this reaction is:

Al(OH)3 + H2SO4 → Al(OH)2SO4 + 2H2O.

3. Cd(HS)2: This compound is called cadmium sulfide. It is formed by the reaction between cadmium chloride and hydrogen sulfide gas. The balanced chemical equation for this reaction is:

CdCl2 + H2S → Cd(HS)2 + 2HCl.

4. Ca(H2PO4)2: This compound is called calcium dihydrogen phosphate or calcium phosphate monobasic. It is formed by the reaction between calcium hydroxide and phosphoric acid. The balanced chemical equation for this reaction is:

Ca(OH)2 + 2H3PO4 → Ca(H2PO4)2 + 2H2O.

5. Al(OH)2NO3: This compound is called aluminum nitrate. It is formed by the reaction between aluminum hydroxide and nitric acid. The balanced chemical equation for this reaction is:

Al(OH)3 + 3HNO3 → Al(NO3)3 + 3H2O.
