Question

Нужно уровнять 1.Гидроксид цинка+азотная кислота 2.Карбонат калия+нитрат бария 3.Оксид натрия+ фосфорная кислота 4.Серебро+нитрат цинка

Answer 1

1. Zn(OH)2 + 2HNO3 =  Zn(NO3)2 + 2H20
2. K2CO3 + Ba(NO3)2 = BaCO3 + 2 KNO3
3.3 Na2O + 2 H3PO4 = 2 Na3PO4 + 3 H2O
4. Ag + ZnNO3 = (Реакция не идёт, Ag слабее чем Zn)

Answer 2

Chemical Equations for Neutralization Reactions

1. Hydroxide of zinc and nitric acid: - The neutralization reaction between hydroxide of zinc and nitric acid can be represented by the chemical equation: ``` Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O [[1]] ```

2. Potassium carbonate and barium nitrate: - The neutralization reaction between potassium carbonate and barium nitrate can be represented by the chemical equation: ``` K2CO3 + Ba(NO3)2 → 2KNO3 + BaCO3 [[2]] ```

3. Sodium oxide and phosphoric acid: - The neutralization reaction between sodium oxide and phosphoric acid can be represented by the chemical equation: ``` Na2O + 2H3PO4 → 2NaH2PO4 [[3]] ```

4. Silver nitrate and zinc: - The reaction between silver nitrate and zinc results in a displacement reaction, not a neutralization reaction. The chemical equation for this reaction is: ``` 2AgNO3 + Zn → Zn(NO3)2 + 2Ag [[4]] ```

These chemical equations represent the neutralization and displacement reactions between the given compounds.
