Question

Решите ионные уравнения

Answer 1

1:
KOH + HCl = KCl + H2O
K + OH + H + Cl = K + Cl + H2O
H + OH = H2O

2:
CaO + 2HNO3 = Ca(NO3)2 + H2O
CaO + 2H + 2NO3 = Ca + 2NO3 + H2O
CaO + 2H = Ca + H2O

3:
CuCl2 + 2KOH = 2KCl + Cu(OH)2
Cu + 2Cl + 2K + 2OH = 2K + 2Cl + Cu(OH)2
Cu + 2OH = Cu(OH)2

4:
Al2(SO4)3 + 3BaCl2 = 3BaSO4 + 2AlCl3
2Al + 3SO4 + 3Ba + 6Cl = 3BaSO4 + 2Al + 6Cl
3Ba + 3SO4 = 3BaSO4
