Question

Закончите схемы возможных реакций, приведите для них молекулярные, полные и краткие ионные уравнения: LiOH+BaCl2=... CuSO4+Zn=...

Answer 1

2LiOH + BaCl2 = Ba(OH)2 + 2LiCl

2Li(+) + 2OH(-) + Ba(+2) + 2Cl(-) = Ba(+2) + 2OH(-) + 2Li(+) + 2Cl(-)

(реакция не идёт)

CuSO4 + Zn = ZnSO4 + Cu

Cu(+2) + SO4(-2) + Zn(0) = Zn(+2) + SO4(-2) + Cu(0)

Cu(+2) + Zn(0) = Zn(+2) + Cu(0)

Answer 2

LiOH + BaCl2 Reaction:

Molecular Equation: The molecular equation for the reaction between LiOH and BaCl2 is: 2LiOH + BaCl2 → 2LiCl + Ba(OH)2 Ionic Equation: The ionic equation for the reaction is: 2Li⁺ + 2OH⁻ + Ba²⁺ + 2Cl⁻ → 2Li⁺ + 2Cl⁻ + Ba(OH)2

Net Ionic Equation: The net ionic equation for the reaction is: 2OH⁻ + Ba²⁺ → Ba(OH)2

CuSO4 + Zn Reaction:

Molecular Equation: The molecular equation for the reaction between CuSO4 and Zn is: CuSO4 + Zn → ZnSO4 + Cu Ionic Equation: The ionic equation for the reaction is: Cu²⁺ + SO4²⁻ + Zn → Zn²⁺ + SO4²⁻ + Cu

Net Ionic Equation: The net ionic equation for the reaction is: Zn + Cu²⁺ → Zn²⁺ + Cu

These are the complete and concise ionic equations for the given reactions. If you have any further questions or need additional information, feel free to ask!
