Question

1) K+ + (OH)- + 2H+ + (SO4)- = 2K+ + (SO4)- + 2H2O
2) 2Na+ + (OH)- + SO2 = 2Na+ + (SO3)-2 + H2O
3) Ca+2 + (OH)- + CO2 = Ca2+ + (CO3)2- + H2O

1) K+ + (OH)- + 2H+ + (SO4)- = 2K+ + (SO4)- + 2H2O
2OH(-)+2H(+)=2H2O-сокращенное
2) 2Na+ + (OH)- + SO2 = 2Na+ + (SO3)-2 + H2O-без изменений
2Na+ + (OH)- + SO2 = 2Na+ + (SO3)-2 + H2O 
3) Ca+2 + (OH)- + CO2 = Ca2+ + (CO3)2- + H2O-без изменений
Ca+2 + (OH)- + CO2 = Ca2+ + (CO3)2- + H2O
