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:
Explanation:
Sodium benzoate forms when benzoic acid reacts with sodium bicarbonate. Since benzoic acid is readily soluble in ether than water, the salt of benzoic is more soluble in water than in ether because it is ionic and very polar. water which is the lower layer will contain sodium benzoate.
After separating the lower layer, if acidified with Hcl,benzoic acid will be regenerated, it precipitates out as a result of its low solubility in water.
Answer:The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.
Explanation:
Answer:
Solid = rocks or other hard stuff
Liquid = water or mild or other stuff likt that
B. elements
It's called the periodic table (of the elements)
