Answer:

Explanation:
Hello,
In this case, for the dissociation of calcium fluoride:

The equilibrium expression is:
![Ksp=[Ca^{2+}][F^-]^2](https://tex.z-dn.net/?f=Ksp%3D%5BCa%5E%7B2%2B%7D%5D%5BF%5E-%5D%5E2)
In such a way, via the ICE procedure, including an initial concentration of calcium of 0.01 M (due to the calcium nitrate solution), the reaction extent
is computed as follows:

Thus, the molar solubility equals the reaction extent
, therefore:

Regards.
Answer:
it's either B. or C.. hope this helps!
Explanation:
the prefix of the second word indicates that a molecule of carbon dioxide indicates that the compound contains two oxygen atoms
I think it would seeing as you typicaly have to use a match to light a gas burner
Ionic, think about the way metals share electrons with other metals, resulting in malleability.
