1) 2HCl+Zn=ZnCl2+H2
2Н(+1) + 2*1е = H2(0)
Zn(0) - 2e= Zn(+2)
2) 6HBr+Al2O3=2AlBr3+3H2O
6H(+) + 6Br(-) + Al2O3 = 2Al(3+) + 6Br(-) + 3H2O
6H(+) +Al2O3 =2Al(3+) + 3H2O
3) 2HI+Cu(OH)2=CuI2+2H2O
2H(+) + 2I(-) + Cu(2+) + 2OH(-) = Cu(2+) + 2I(-) + 2H2O
2H(+) + 2OH(-) =2H2O
4) 2HCl+Na2CO3=2NaCl+H2O+CO2
2H(+) + 2Cl(-) + 2Na(+) + CO3(2-) = 2Na(+) +
2Cl(-) + H2O + CO2
2H(+) + CO3(2-) = H2O + CO2

1) 2HCl+Zn=ZnCl2+H22Н(+1) + 2*1е = H2(0)
Zn(0) - 2e= Zn(+2)
2) 6HBr+Al2O3=2AlBr3+3H2O
6H(+) + 6Br(-) + Al2O3 = 2Al(3+) + 6Br(-) + 3H2O
6H(+) +Al2O3 =2Al(3+) + 3H2O
3) 2HI+Cu(OH)2=CuI2+2H2O
2H(+) + 2I(-) + Cu(2+) + 2OH(-) = Cu(2+) + 2I(-) + 2H2O
2H(+) + 2OH(-) =2H2O
4) 2HCl+Na2CO3=2NaCl+H2O+CO2
2H(+) + 2Cl(-) + 2Na(+) + CO3(2-) = 2Na(+) +
2Cl(-) + H2O + CO2
2H(+) + CO3(2-) = H2O + CO2
