Which correctly describes the location and charge of the electrons in an atom

Dmitry [639]

Hey there!

Electrons are negatively charged and orbit the nucleus of the atom on energy levels (kind of in a cloud) :)

CdF2(s)⇄Cd2+(aq)+2F−(aq)A saturated aqueous solution of CdF2 is prepared. The equilibrium in the solution is represented above.

kupik [55]

Answer:

The correct answer is option a.

Explanation:

$CdF_2(s)\rightleftharpoons Cd^{2+}(aq)+2F^-(aq)$

Equilibrium concentration cadmium ions = $[Cd^{2+}]=0.0585 M$

Equilibrium concentration fluoride ions = $[F^{-}]=0.117 M$

Molar solubility is the maximum concentration of salt present in water in ionic form beyond that no more salt will exist in its ionic form and will settle down in bottom of the solution.

The molar solubility of the solid cadmium fluoride = 0.0585 M

$CdF_2(s)\rightleftharpoons Cd^{2+}(aq)+2F^-(aq)$ ..[1]

$NaF(s)\rightleftharpoons Na^{+}(aq)+F^-(aq)$

Due to addition of sodium fluoride will increase concentration of fluoride in the solution.And due to common ion effect the equilibrium will shift in backward direction in [1], that is precipitation of more cadmium fluoride.

Hence, decrease in solubility will be observed.

Why is the chlorine that is added to final,

dsp73

Chlorine is used as a disinfectant to wastewater treatment plants. The addition of chlorine to the final treated water is because to make sure that some of the microorganisms not killed during treatment is eliminated. It is consumed before it is released to the environment to ensure that microorganisms and other marine life are not killed in the process too.
