Question

Записать реакцию Ca(OH)2 --> CaCl2 в ионном и молекулярном виде.

Answer 1

Ca(OH)₂ + 2HCl = CaCl₂ + 2H₂O;
Ca²⁺ + 2OH⁻ + 2H⁺ + 2Cl⁻ = Ca²⁺ + 2Cl⁻ + 2H₂O;
2OH⁻ + 2H⁺ = 2H₂O.

Answer 2

Reaction: Ca(OH)2 -> CaCl2

The reaction you provided is the conversion of calcium hydroxide (Ca(OH)2) to calcium chloride (CaCl2). Let's write the reaction in both ionic and molecular forms.

Ionic Equation: Ca(OH)2 (aq) -> Ca^2+ (aq) + 2OH^- (aq)

Molecular Equation: Ca(OH)2 (aq) -> CaCl2 (aq)

In the ionic equation, Ca(OH)2 dissociates into Ca^2+ and 2OH^- ions. The molecular equation simply represents the overall reaction without showing the dissociation of the compounds into ions.

Please note that the reaction you provided is incomplete, as it does not include the reactants or conditions under which the reaction occurs. If you have any additional information or specific conditions for the reaction, please let me know, and I'll be happy to assist you further.
