Write balanced complete ionic equation for CaS(aq) + CaCl2 (aq) –> CdS(s) + CaCl2 (aq).

Express your answer as a chemical equation. Identify all of the phases in your answer.​

Ca²⁺(aq) + S²⁺(aq) + Cd²⁺(aq) + 2Cl¯(aq) —> CdS (s) + Ca²⁺(aq) + 2Cl¯(aq)

Explanation:

CaS (aq) + CdCl₂ (aq) –> CdS (s) + CaCl₂ (aq)

The complete ionic equation for the above reaction can be obtained as illustrated below:

In solution:

CaS (aq) —> Ca²⁺(aq) + S²⁺(aq)

CdCl₂ (aq) —> Cd²⁺(aq) + 2Cl¯(aq)

CaS (aq) + CdCl₂ (aq) –>

Ca²⁺(aq) + S²⁺(aq) + Cd²⁺(aq) + 2Cl¯(aq) —> CdS (s) + Ca²⁺(aq) + 2Cl¯(aq)

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
