«Цепочки переходов» по теме «Неметаллы». 1.O2→NО→NО2→HNO3→Mg(NO3)2→HNO3 2.Сl2→ HCl → ZnCl2→ AgCl ↓ NaCl

Answer 1

1.1)O2+N2=(кат.,t)=2NO
2)2NO+O2=(кат.,t)=2NO2
3)2NO2+H2O=HNO3+HNO2
4)Mg(OH)2+2HNO3=Mg(NO3)2+2H2O
5)Mg(NO3)2+2NaOH=Mg(OH)2↓+2HNO3
2.1)Cl2+H2=2HCl
2)Zn+2HCl=ZnCl2+H2↑
3)ZnCl2+2AgNO3=Zn(NO3)2+2AgCl↓↓
Cl2+2NaBr=2NaCl+Br2

Answer 2

1. O2 → NО → NО2 → HNO3 → Mg(NO3)2 → HNO3 2. Сl2 → HCl → ZnCl2 → AgCl ↓ NaCl

Let's break down each of these chains of reactions:

1. O2 → NО → NО2 → HNO3 → Mg(NO3)2 → HNO3 - The first reaction is the formation of nitrogen monoxide (NO) from oxygen (O2). - The second reaction is the oxidation of nitrogen monoxide (NO) to nitrogen dioxide (NO2). - The third reaction involves the conversion of nitrogen dioxide (NO2) to nitric acid (HNO3). - The fourth reaction is the reaction between nitric acid (HNO3) and magnesium (Mg) to form magnesium nitrate (Mg(NO3)2). - The fifth reaction is the reaction between magnesium nitrate (Mg(NO3)2) and nitric acid (HNO3). - Please note that the specific conditions and catalysts for these reactions are not provided, so it's important to consider that these reactions may require specific conditions or catalysts to occur.

2. Сl2 → HCl → ZnCl2 → AgCl ↓ NaCl - The first reaction is the reaction between chlorine gas (Cl2) and hydrogen gas (H2) to form hydrogen chloride (HCl). - The second reaction is the reaction between hydrogen chloride (HCl) and zinc (Zn) to form zinc chloride (ZnCl2). - The third reaction is the reaction between zinc chloride (ZnCl2) and silver nitrate (AgNO3) to form silver chloride (AgCl) and sodium nitrate (NaNO3). - The downward arrow (↓) indicates that silver chloride (AgCl) is less soluble than sodium chloride (NaCl), causing it to precipitate out of the solution.
