б)Ca(OH)2+2CO2=Ca(HCO3)2
Ca(OH)2+2CO2=Ca(2+)+2HCO3(-)или так
б)Ca(OH)2 + CO2 = CaCO3↓ + H2O
Ca(2+) + 2OH(-) + CO2 = CaCO3↓ + H2O
в)Fe(OH)2+H2SO4=FeSO4+2H2O
Fe(OH)2+2H(+)+SO4(2-)=Fe(2+)+SO4(2-)+2H2O
Fe(OH)2+2H(+)=Fe(2+)+2H2O
г)FeCl3 + 3RbOH = Fe(OH)3 + 3RbCl Fe(3+) + 3Cl(-) + 3Rb(+) + 3OH(-) = Fe(OH)3 + 3Rb(+) + 3Cl(-) Fe(3+) + 3OH(- )= Fe(OH)3
е)Ba(OH)2+N2O5=Ba(NO3)2+H2O
Ba(OH)2+N2O5=Ba(2+)+2NO3(-)+H2O
