Question

Пожалуйста помогите решить!

Answer 1

Na2o+2HF->2NaF+H2O
2Li+2HCl->2LiCl+H2
BaCl2+H2SO4->BaSO4+2HCl
2LiOH+H2S->Li2S+2H2O
Zn+H2SO4->ZnSO4+H2(или же 3Zn+4H2SO4->3ZnSO4+S+4H2O)
Cu(OH)2+2HNO3->Cu(NO3)2+2H2O
AgNO3+HI->AgI+HNO3
3K2O+2H3PO4->2K3PO4+3H2O

Answer 2

1 вариант
NaO+HF=H20+NaF
2LI+2HCL=2LICL+H2
BACL2+H2SO4=2HCL+BASO4
2LIOH+H2S=2H2O+LI2S
Zn+H2SO4=H2+ZnSO4
CU(OH)2+2HNO3=2H20+CU(NO3)2
AgNO3+HY=AgY+HNO3
3K2O+2H3PO4=2k3po4+3h2o
