Answer 1

Приветствую!
1. 3Na₂O + P₂O₅ = 2Na₃PO₄
2. SiO₂ + 2KOH =K₂SiO₃↓+ H₂O
3. 2Zn(OH)₂ + CO₂ = Zn₂CO₃(OH)₂↓ + H₂O
4. 2LiOH + CO₂ = Li₂CO₃↓ + H₂O

Answer 2

The chemical reactions you provided involve various compounds and elements. Let's break down each reaction step by step:

1. Na2O + P2O5: This is a combination of sodium oxide (Na2O) and diphosphorus pentoxide (P2O5). When these compounds react, they form sodium metaphosphate, NaPO3.

   Na2O + P2O5 → 2NaPO3

2. SiO2 + KOH: This is a combination of silicon dioxide (SiO2) and potassium hydroxide (KOH). When these compounds react, they form potassium silicate (K2SiO3) and water (H2O).

   SiO2 + 2KOH → K2SiO3 + H2O

3. CO2 + Zn(OH)2: This is a combination of carbon dioxide (CO2) and zinc hydroxide (Zn(OH)2). When these compounds react, they form zinc carbonate (ZnCO3) and water (H2O).

   CO2 + Zn(OH)2 → ZnCO3 + H2O

4. LiOH + SO2: This is a combination of lithium hydroxide (LiOH) and sulfur dioxide (SO2). When these compounds react, they form lithium sulfite (Li2SO3).

   2LiOH + SO2 → Li2SO3 + H2O

So, the products of these reactions are:

1. Na2O + P2O5 → 2NaPO3
2. SiO2 + 2KOH → K2SiO3 + H2O
3. CO2 + Zn(OH)2 → ZnCO3 + H2O
4. 2LiOH + SO2 → Li2SO3 + H2O
