Question

распишите на ионы:
1.Cu+2HCl=CuCl2 + H2
2.Zn+2HCl=ZnCl2 + H2
3.AgNO3+HCl=AgCl + HNO3

Answer 1

1. Cu+2HCL=CuCl2+H2↑
    Cu+2H⁺+2Cl⁻=Cu²⁺+2Cl⁻+H2↑
    Cu+2H⁺=Cu²⁺+H2↑
2. Zn+2HCl=ZnCl2+H2↑
    Zn+2H⁺+2Cl⁻=Zn²⁺+2Cl⁻+H2↑
    Zn+2H⁺=Zn²⁺+H2↑
3. AgNO3+HCl=AgCl↓+HNO3
    Ag⁺+NO3⁻+H⁺+Cl⁻=AgCl↓+H⁺+NO3⁻
   Ag⁺+Cl⁻=AgCl↓
