Question

Составте уравнение химических реакций по цепочке превращения Nao->Nacl -> Naon->Na | NaoH->na2so4 ->nano4 приведите название веществ. пожалуйстаааа помогите

Answer 1

Na2o+2HCl=NaCl+H2O из оксида натрия получаем хлорид натрия
NaCl+KOH=NaOH+KCl из  хлорида натрия получаем гидрооксид натрия
NaOH+K=KOH+Na 
Na2O+H2O=2NaOH
2Naoh+H2SO4=Na2SO4+2HOH
 наверно последняя реакция NaNO3
 Na2SO4+2KNO3=2NaNO3+K2SO4

Answer 2

Chemical Equation:

The chemical reactions can be represented by the following equations:

1. Sodium oxide (Na2O) reacts with hydrochloric acid (HCl) to form sodium chloride (NaCl) and water (H2O): ``` Na2O + 2HCl → 2NaCl + H2O ```

2. Sodium chloride (NaCl) reacts with sodium hydroxide (NaOH) to form sodium hypochlorite (NaOCl) and water (H2O): ``` NaCl + NaOH → NaOCl + H2O ```

3. Sodium hypochlorite (NaOCl) reacts with sodium hydroxide (NaOH) to form sodium chlorate (NaClO3) and water (H2O): ``` NaOCl + NaOH → NaClO3 + H2O ```

4. Sodium chlorate (NaClO3) reacts with sulfuric acid (H2SO4) to form sodium sulfate (Na2SO4), chlorine gas (Cl2), and water (H2O): ``` 2NaClO3 + H2SO4 → Na2SO4 + 2Cl2 + H2O ```

5. Sodium sulfate (Na2SO4) reacts with sodium hydroxide (NaOH) to form sodium nitrate (NaNO3) and water (H2O): ``` Na2SO4 + 2NaOH → 2NaNO3 + H2O ```

Substance Names:

The substances involved in the reactions are:

- Sodium oxide (Na2O) - Hydrochloric acid (HCl) - Sodium chloride (NaCl) - Water (H2O) - Sodium hydroxide (NaOH) - Sodium hypochlorite (NaOCl) - Sodium chlorate (NaClO3) - Sulfuric acid (H2SO4) - Chlorine gas (Cl2) - Sodium sulfate (Na2SO4) - Sodium nitrate (NaNO3)

Please note that the names of the substances are provided based on the given chemical equations.
