Question

Na2O2→Na2O→NaOH→NaCl+NaNO3

Answer 1

Привет! Сейчас решим

Na2O2 + 2Na = 2Na2O

Na2O + H2O = 2NaOH

NaOH + HCl = NaCl + H2O

NaCl + AgNO3 = NaNO3 + AgCl(осад.)

Answer 2

The chemical equation you provided shows a series of reactions starting with Na2O2 and ending with NaCl and NaNO3. Let's break down each step:

1. Na2O2 → Na2O: This reaction involves the decomposition of sodium peroxide (Na2O2) into sodium oxide (Na2O). The balanced equation for this reaction is: 2 Na2O2 → 2 Na2O + O2

2. Na2O → NaOH: The second reaction is the reaction of sodium oxide (Na2O) with water (H2O) to form sodium hydroxide (NaOH). The balanced equation for this reaction is: Na2O + H2O → 2 NaOH

3. NaOH → NaCl + NaNO3: The third reaction involves the reaction of sodium hydroxide (NaOH) with hydrochloric acid (HCl) and nitric acid (HNO3), resulting in the formation of sodium chloride (NaCl) and sodium nitrate (NaNO3). The balanced equation for this reaction is: NaOH + HCl + HNO3 → NaCl + NaNO3 + H2O

So, when you combine all the reactions together, you get the following overall reaction: 2 Na2O2 + 2 H2O + 2 HCl + 2 HNO3 → 2 NaCl + 2 NaNO3 + 3 O2 + 4 NaOH

Please note that the reaction conditions (such as temperature, pressure, etc.) are not specified in your question, so these reactions are assumed to occur under standard conditions.
