Question

Решите уравнения по химии:
1. Ba(NO3)2+K2SO4=
2.AgNO3+CaCl2=
3. AgNO3+ Na3PO4

Answer 1

1)Ba(NO3)2+K2SO4 = BaSO4+2KNO3
2)2AgNO3+CaCl2+2AgCl+Ca(NO3)2
3)3AgNO3+Na3PO4=Ag3PO4+3NaNO3

Answer 2

1. Ba(NO3)2 + K2SO4 = BaSO4↓ + 2KNO3
Ba²⁺+2NO₃⁻+2K⁺+SO₄²⁻ = BaSO₄↓ + 2K⁺+2NO₃⁻
Ba²⁺+SO₄²⁻ = BaSO₄↓
2.
2AgNO3 + CaCl2 = 2AgCl↓ + Ca(NO3)2
2Ag⁺+2NO₃⁻+Ca²⁺+2Cl⁻ = 2AgCl↓ + Ca²⁺ + 2NO₃⁻
2Ag⁺+2Cl⁻=2AgCl↓
3.
3AgNO3 + Na3PO4 = Ag3PO4↓ + 3NaNO3
3Ag⁺ + 3NO₃⁻ + 3Na⁺ + PO₄³⁻ = Ag₃PO₄↓ + 3Na⁺+3NO₃⁻
3Ag⁺+PO₄³⁻ = Ag₃PO₄↓
