Объяснение:
MnCl2+ Na2S = MnS↓ + 2NaCl
Mn(2+) + 2Cl(-) + 2Na(+) + S(2-) = MnS↓ + 2Na(+) + 2Cl(-)
Mn(2+) + S(2-) = MnS↓
Al(OH)3 + 3HCl = AlCL3 + 3H2O
Al(OH)3 + 3H(+) + 3Cl(-) = Al(3+) + 3Cl(-)+ 3H2O
Al(OH)3 + 3H(+)= Al(3+) + 3H2O
CH3COONa + HCl = CH3COOH + NaCl
CH3COO(-) + Na(+) + H(+) + Cl(-) = CH3COOH + Na(+) + Cl(-)
CH3COO(-) + H(+) = CH3COOH
