Answer:
20 mL OF 6 M HYDROCHLORIC ACID WILL BE NEEDED
Explanation:
M1 V1 = M2 V2
M1 = Molarity of sodium hydroxide = 3 M
V1 = volume of sodium hydroxide = 40 mL
M2 = Molarity of hydrochloric acid = 6 M
V2 = Volume of hydrochloric acid = unknown
Rearranging the equation, we have:
V2 = M1 V1 / M2
V2 = 3 * 40 mL / 6
V2 = 120 / 6
V2 = 20 mL
To precipitate the benzoic acid by 6 M of hydrochloric acid, 20 mL volume will be needed.

I thought the answer was " T R A N S P A R E N T " but I don't know what the extra two letters are! I'm sorry, that's all I've got..
The answer should be A. NW Hemisphere
Taking the compound with the metallic counterpart of highest mass would be the answer. Looking at the periodic table, it is easy to realize that K has the highest mass out of H, Li, K, and Cl. Therefore, the answer is (2) KCl.
