6) A solution with oply tvo components must alway a. TRUE b BALSE 7) A stock aqueous solution contains 503.29 grams of Nacl pe 1.000 liter. 81.00 ml.a.of water is added to 10. (YOU MUST SHOW YOUR WORK ON ATTACHED SHEES 00 mLs of the stock solution. What is the molarity of the dilution? PLACE ANSWER HERE Reduction i s the process whereby a reactant in a reaction loses one or more electrons. b. FALSE a. TRUE the solubility rule "like dissolves like" is not adequate for predicting solubilities wh a. molecular solid solute is a(n) b, ionic soli solid

Explanation / Answer

6)False

7)Molecular weight of NaCl =58.4g/mol

58.4g Nacl=1mol NaCl

503.29 g NaCl=8.618 mol NaCl

molarity=moles of solute/liters of solution

in 1 litre there is 8.618 mol

so,in 10 ml there is .08618 mol NaCl

total olume=10ml+81ml=91ml=.091L

molarity=.08618/.091=.947M

8)False.

because reduction is a process where electrons are added to ions or atoms.

9)The solubility rule like dissolves like is not adequate for predicting the solubilities when solute is an ionic solid.
