Объяснение:

1)

AlCl₃ + 3 AgNO₃ = 3 AgCl ↓ + Al(NO₃)₃

Al³⁺ + 3 Cl⁻ + 3 Ag⁺ + 3 NO₃⁻ = 3 AgCl ↓ + Al³⁺ + 3 NO₃⁻

Cl⁻ + Ag⁺  = AgCl ↓

2)

FeCl₃ + 3KOH = Fe(OH)₃↓ + 3KCl

Fe³⁺ + 3Cl⁻  + 3K⁺ + 3OH⁻ = Fe(OH)₃ + 3K⁺ + 3Cl⁻

Fe³⁺ + 3OH⁻ = Fe(OH)₃

3)

Al(NO₃)₃ + 3KOH =  Al(OH)₃↓ + 3KNO₃

Al³⁺ + 3NO₃⁻ + 3K⁺ + 3OH⁻ = Al(OH)₃↓+ 3K⁺ + 3NO₃⁻

Al³⁺ + 3OH⁻ = Al(OH)₃↓

4)

К₂S + Pb(NO₃)⁻¹₂=2KNO₃ + PbS↓

2K⁺ + S²⁻ + Pb²⁺ + 2NO₃⁻ = 2K⁺ +2NO₃⁻ + Pb²⁺ + S²⁻ ↓

S⁻²+ Pb²⁺ = PbS↓

5)

Na₂SiO₃ + 2HCl = H₂SiO₃↓ + 2NaCl

2Na⁺ + SiO₃²⁻ + 2H⁺ + 2Cl⁻ = H₂SiO₃↓ + 2Na⁺ + 2Cl⁻

2H⁺ + SiO₃²⁻ = H₂SiO₃↓

6)

ZnCl₂ + Ba(OH)₂ = Zn(OH)₂ + BaCl₂

Zn²⁺ + 2 Cl ⁻ + Ba²⁺+ 2(OH ⁻ = Zn(OH)₂ + Ba²⁺ + 2 Cl ⁻

Zn²⁺ + 2 OH⁻ = Zn(OH)₂

7)

2Na₃PO₄ + 3CaCl₂ = Ca₃(PO₄)₂↓ + 6NaCl

6Na⁺ + 2PO₄³⁻ + 3Ca²⁺ + 6Cl⁻ = Ca₃(PO₄)₂↓ + 6Na⁺ + 6Cl⁻

3Ca²⁺ +  2PO₄³⁻ = Ca₃(PO₄)₂↓
