Answer 1

Ответ:

Объяснение:

3KOH + AlCl3 = Al(OH)3↓ + 3KCl

CH4 + 2O2 = CO2↑ + 2H2O

FeO + 2HCl = FeCl2 + H2O

P2O5 + 3H2O = 2H3PO4

Ag2O + 2HCl = 2AgCl + H2O

Na2O + CO2 = Na2CO3

2KClO3 -> 2KCl + 3O2

2HClO3 -> 2HCl + 3O2

3Mg + N2 = Mg3N2

Mg(OH)2 -> MgO + H2O

H2O + SO3 = H2SO4

CaCO3 -> CaO + CO2

Answer 2

Let's balance the given chemical equations:

1. KOH + AlCl₃ → Al(OH)₃ + KCl

2. CH₄ + 2O₂ → CO₂ + 2H₂O

3. FeO + 2HCl → FeCl₂ + H₂

4. 2KClO₃ → 2KCl + 3O₂

5. 3Mg + N₂ → Mg₃N₂

6. H₂O + SO₃ → H₂SO₄

7. Ag₂O + 2HCl → 2AgCl + H₂O

8. P₂O₅ + 3H₂O → 2H₃PO₄

9. Na₂O + CO₂ → Na₂CO₃

10. 2HClO₃ → 2HCl + 3O₂

11. Mg(OH)₂ → MgO + H₂O

12. CaCO₃ → CaO + CO₂

I have balanced the equations according to the conservation of mass and charge.
