Question

решите уравнения:

1)Ca(OH)2+CO2=

2)Zn+HCl=

3)Al2O3+H2SO4=

4)BaSo4+HCl=

5)Cu(OH)2=

6)SO2+NaOH=

7)N2O5+KOH=

Answer 1

Сa(OH)2 + 2CO2 = 2CaCO3 + H2

Zn + HCl = H + ZnCl2

Al2O3 + 3H2SO4 = Al2(SO4)3 + 3H20

BaSO4 + 2HCl = BaCl2 + H2SO4

2CuOH2 = 2CuO + 2H2

SO2 + NaOH = NaHSO3

N2O5 + 2KOH = K2O + N2O + H2
