Multiple Choice
Сокращенное ионное уравнение реакции
Zn +HCl = ZnCl2 +H2
Zn2++ 2Cl- = ZnCl2
O2- +2H+ = 2H2O
Zn0 +2H+ =Zn2+ + H20
Zn2+ + H20 = Zn0 +2H+

Multiple Choice
Сокращенное ионное уравнение реакции
ZnO + HCl = ZnCl2 +H2O
Zn2++ 2Cl- = ZnCl2
Zn0 +2H+ =Zn2+ + H20
Zn2+ + H20 = Zn0 +2H+
ZnO +2H+ =Zn2+ H2O

Multiple Choice
Сокращенное ионное уравнение реакции
NaOH +HCl = NaCl +H2O
Na+ +Cl- = NaCl
OH- + H+ =H2O
Na+ +OH- = NaOH
H+ +Cl- =HCl

Multiple Choice
Сокращенное ионное уравнение реакции
Na2CO3 + HCl= NaCl + CO2 +H2O
CO32- +2H+ =CO2 +H2O
2Na+ +2Cl- = 2NaCl
2Na+ + CO32- = Na2CO3
Na+ +H- = NaH
