Answer: The solubility of this compound in pure water is 0.012 M
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the is given as:
By stoichiometry of the reaction:
1 mole of
gives 1 mole of
and 2 mole of
When the solubility of
is S moles/liter, then the solubility of
will be S moles\liter and solubility of
will be 2S moles/liter.
![6.5\times 10^{-6}=[S][2S]^2](https://tex.z-dn.net/?f=6.5%5Ctimes%2010%5E%7B-6%7D%3D%5BS%5D%5B2S%5D%5E2)
Thus solubility of this compound in pure water is 0.012 M
Answer: The correct answer is C) carbon dioxide; calcium.
Explanation:
Carbonated soft drinks contain big concentrations of carbon dioxide, which is the bubbles that we see and feel. When these drinks are included regurly in the diet, the carbon dioxide levels are increased; and according to several studies high carbon dioxide values are related with bone loss.
Additionally, calcium is known for being an important nutrient for both formation and maintenance of bones, so inadequate intake of calcium in the diet results in a bone loss.
The only list containing molecules is list #4
NaCl, N2, and H2O are all made up of more than one element, making them molecules. The other lists contain an element. Mg, He, and Fe are elements, not molecules.
Hope this helps!
