Морозов Никита

а) Pb(NO3)2+2NaI=PbI2+2NaNO3n
Pb(2+)+2NO3(-)+2Na(+)+2I(-)=2Na(+)+2NO3(-)+PbI2n
Pb(2+)+2I(-)=PbI2n
б) KOH+HCl=KCl+H2On
K(+)+Cl(-)+H(+)+OH(-)=K(+)+Cl(-)+H2On
H+ + OH- = H2On
в) (NH4)2CO3+H2SO4=(NH4)2SO4+H2O+CO2n
2NH4(+)+CO3(2-)+2H(+)+SO4(2-)=2NH4(+)+SO4(2-)+H2O+CO2n
CO3 2- + 2H+ = H2O + CO2n
г) 2FeCl3+3Ba(OH)2=2Fe(OH)3+3BaCl2n
2Fe(3+)+6Cl(-)+3Ba(2+)+6OH(-)=2Fe(OH)3+3Ba(2+)+6Cl(-)n
Fe 3+ + 3OH- = Fe(OH)3
