Сокращенное ионное уравнение реакции
Сa(OH)2 +2HCl = CaCl2 +2H2O :
Сa(OH)2 + 2H+ = Ca2+ +2H2O
2OH- + 2H+ =2H2O
Ca2+ +2Cl- =CaCl2
Ca2+ +2OH- =Ca(OH)2

Multiple Choice
Сокращенное ионное уравнение реакции
Сa(OH)2 + N2O5 = Ca(NO3)2 +H2O
Ca2+ +N2O5 = Ca(NO3)2
2OH- + N2O5 = 2NO3- +H2O
Ca(OH)2 + N2O5 = Ca(NO3)2 + H2
Ca(OH)2 + N2O5 = Ca(NO3)2 + H2O
Определите характер оксидов щелочноземельных металлов.
