The option that identifies the molar solubility of CdF₂ in pure water is;
A: The molar solubility of CdF₂ in pure water is 0.0585M, and adding NaF decreases this solubility because the equilibrium shifts to favor the precipitation of some CdF₂.
<h3>Understanding Molar Solubility</h3>
The equation of this reaction is;
CdF₂ (s) ⇄ Cd²⁺ (aq) + 2F⁻ (aq)
We are told that;
[Cd²⁺] (eq) = 0.0585m and [F⁻] eq = 0.117m.
Also, we see that 0.90m NaF is added to the saturated solution.
Now, molar solubility is defined as the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
Thus, we can conclude that The molar solubility of CdF₂ in pure water is 0.0585M, and adding NaF decreases this solubility because the equilibrium shifts to favor the precipitation of some CdF₂.

Answer:
The constitution reflects a desire to protect our rights. We still have the same constitution up to this day, so the goverment does seek the same goal.
Explanation:
The constitution states That when a goverment becomes destructive to these ends, it is the duty of the people to "alter or abolish it". When the goal is other then to protect our rights, this goverments must be replaced or removed, but we must always have a goverment, who's goal is to do so.
Answer:
It's wrong.
Explanation:
In the Punnett square, we will use F to represent the dominant freckles gene and f to represent the recessive lack-of-freckles gene. The first individual would have FF, because homozygous means that both alleles are the same. The second individual would have Ff, because heterozygous means that it has 2 different alleles. If the first individual passes down one of its "F" alleles and the second individual passes down its "F" allele, the offspring would have 2 dominant alleles, and the researcher's conclusion is disproven.
