Правильно ли я составила ионные уравнения? подскажите пожалуйста 1)
2НCl + Zn = ZnCl2 + H2
2H+ + 2Cl- + Zn0 =Zn2+ +2Cl- +H20
2H+ + Zn0 = Zn2+ + H20
2)
H2SO4 + Na2O = Na2SO4 + H2O
2H+ + SO42- + Na2O = 2Na+ + SO42- + H2O
2H+ + Na2O = 2Na+ + H2O
3)
2HNO₃ + Ba(OH)₂ = Ba(NO₃)₂ + 2H₂O
2H+ + 2NO3- + Ba(OH)2 = Ba2+ + 2NO3- + 2H2O
2H+ + Ba(OH)2 = Ba2+ + 2H2O
4)
2HCl + K2CO3 = 2KCl + H2CO3
2H⁺ + 2Cl⁻ + 2K⁺ + CO₃²⁻ = 2K⁺ + 2Cl⁻ + H₂O + CO₂
2H⁺ + CO₃²⁻ = H₂O + CO₂
