Question

B) Na₂O → NaOH → Na₂CO3 → NaCl → NaNO3;​

Answer 1

Ответ:

1) Na2O + H2O = 2NaOH
2) 2 NaOH + H2CO3 = Na2CO3 + 2 H2O
3) Na2CO3 + 2 HCl = 2 NaCl + H2O + CO2↑
4) NaCl + HNO3 = NaNO3 + HCl

Answer 2

The given sequence represents a series of chemical reactions involving the compound sodium oxide (Na₂O) and various reagents to produce different sodium compounds. Let's break down the reactions step by step:

1. Na₂O → NaOH: In this reaction, sodium oxide (Na₂O) reacts with water (H₂O) to produce sodium hydroxide (NaOH). The chemical equation for this reaction is: Na₂O + H₂O → 2NaOH

2. NaOH → Na₂CO₃: Sodium hydroxide (NaOH) reacts with carbon dioxide (CO₂) to form sodium carbonate (Na₂CO₃). This reaction is known as the Solvay process and is used industrially to produce sodium carbonate. The chemical equation is: 2NaOH + CO₂ → Na₂CO₃ + H₂O

3. Na₂CO₃ → NaCl: Sodium carbonate (Na₂CO₃) can react with hydrochloric acid (HCl) to produce sodium chloride (NaCl), carbon dioxide (CO₂), and water (H₂O). The chemical equation is: Na₂CO₃ + 2HCl → 2NaCl + CO₂ + H₂O

4. NaCl → NaNO₃: Sodium chloride (NaCl) can undergo a reaction with nitric acid (HNO₃) to produce sodium nitrate (NaNO₃), hydrochloric acid (HCl), and water (H₂O). The chemical equation is: NaCl + HNO₃ → NaNO₃ + HCl + H₂O

So, the complete sequence of reactions is: Na₂O → NaOH → Na₂CO₃ → NaCl → NaNO₃. Each reaction represents a transformation of the previous compound into a new compound by reacting with specific reagents.
