Полное и сокращенное ионное уравнение, сколько сможете !! Срочно !!! 2KCl + Na3[Co(NO2)6] = K3Na[Co(NO2)6] осадок + 2NaCl . MgCl2 + Na2HPO4 + NH4OH = MgNH4PO4 осадок + 2NaCl .
CaCl2 + (NH4)2C2O4 = CaC2O4 (осадок) + 2NH4Cl-

Ага! Только пойдет ли данная реакция в реальных условиях?

Тоже думала над этим. Похоже, что высосали из пальца...

2KCl + Na₃[Co(NO₂)₆] = K₂Na[Co(NO₂)₆]↓ + 2NaCl;
2K⁺ + 2Cl⁻ + 3Na⁺ + [Co(NO₂)₆]³⁻ = K₂Na[Co(NO₂)₆]↓ + 2Na⁺ + 2Cl⁻;
2K⁺ + Na⁺ + [Co(NO₂)₆] = K₂Na[Co(NO₂)₆]↓.
MgCl₂ + Na₂HPO₄ + NH₄OH = MgNH₄PO₄↓ + 2NaCl + H₂O;
Mg²⁺ + 2Cl⁻ + 2Na⁺ + HPO₄²⁻ + NH₄⁺ + OH⁻ = MgNH₄PO₄↓ + 2Na⁺ + 2Cl⁻ + H₂O;
Mg²⁺ + HPO₄²⁻ + NH₄ + OH⁻ = MgNH₄PO₄↓ + H₂O.
CaCl₂ + (NH₄)₂C₂O₄ = CaC₂O₄↓ + 2NH₄Cl;
Ca²⁺ + 2Cl⁻ + 2NH₄⁺ + C₂O₄²⁻ = CaC₂O₄↓ + 2NH₄⁺ + 2Cl⁻;
Ca²⁺ + C₂O₄²⁻ = CaC₂O₄↓.
ПОТНО.

1) Na₃[Co(NO₂)₆] + 2 KCl → K₂Na[Co(NO₂)₆] ↓+ 2NaCl
3Na⁺ + [Co(NO₂)₆}³⁻ + 2K⁺+ 2Cl⁻ → K₂Na[Co(NO₂)₆] ↓+ 2Na⁺ + 2Cl⁻
Na⁺ + [Co(NO₂)₆}³⁻ + 2K⁺ → K₂Na[Co(NO₂)₆] ↓
2) MgCl₂ + Na₂HPO₄ + NH₄OH = MgNH₄PO₄ ↓ + 2NaCl + H₂O (в этом уравнении вода прямо просится для уравнивания)
Mg²⁺ + 2Cl⁻ + 2Na⁺ + HPO₄²⁻ + NH₄⁺ + OH⁻= MgNH₄PO₄ ↓ + 2Na⁺+ 2Cl⁻ +H₂O
Mg²⁺ + HPO₄²⁻ + NH₄⁺ + OH⁻= MgNH₄PO₄ ↓ + H₂O
3) CaCl₂ + (NH₄)₂C₂O₄ = CaC₂O₄↓ + 2NH₄Cl
Ca²⁺ + 2Cl⁻ + 2NH₄⁺ + C₂O₄²⁻ = CaC₂O₄↓ + 2NH₄⁺ + 2Cl⁻
Ca²⁺ + C₂O₄²⁻ = CaC₂O₄↓
