To calculate the solubility product, Ksp, of the compound Ag2CrO4. We need its dissociation reaction and the concentration of each ion in the solution. Since the concentration is not given then we can only show an expression for the calculation of such.
Ag2CrO4<span> > 2Ag+ + CrO4-2
</span>
Ksp = [Ag+]² [<span>CrO4 2-] </span>
Answer:
The appropriate option will be Option A (unequal sharing of electrons in a covalent bond).
Explanation:
- A polar bond seems to be a covalent bond amongst two or even more atoms where there is an uneven distribution of the electrons surrounding the connection.
- This induces a small electrical magnetic dipole in the molecules whereby the end becomes generally favorable and another is mildly controversial.
The other choices aren't relevant to the situation presented. The answer above would be appropriate.
The molar mass of calcium carbonate is 100 mg/mmol, so the
number of moles is:
moles CaCO3 = 500 mg / (100 mg/mmol) = 5 mmol
We see that there is 1 mole of Ca per 1 mole of CaCO3,
therefore:
<span>mass Ca = 5 mmol * (40.08 mg/mmol) = 200.22 mg</span>
I can describe one prop. of energy: it can not be created or destroyed. It can be transferred, or converted, though.
