Answer:
c) removing fluoride ions.
Explanation:
Hello!
In this case, for this solubility product problem, it is very convenient to write the undergoing ionization reaction:

In such a way, via the Le Chatelier's principle, we remember that the addition of reactants shifts the reaction towards products, adding products shifts the reaction towards reactants, removing reactants shifts the reaction towards reactants and removing products shifts the reaction towards products. In means, that the best way to shift this reaction away from solid calcium fluoride and toward the dissolved ions is c) removing fluoride ions, because it is a product and its removal favors the formation of more products.
Best regards!
Answer:
Lead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table.
Answer:
130,000 cubic centimeters
Explanation:
The volume of a box is its length multiplied by its width multiplied by its height (lwh). 423 times 12 times 25 is 126,900. When multiplying, the number of significant figures is the same as the number with the least number of significant figures. The correct number of significant figures in this example is 2, so 126,900 would need to round up to 130,000 in order to have 2 significant figures.
