(about SEPARATION OF BENZOIC ACID AND NAPHTHALENE BY LIQUID-LIQUID EXTRACTION) a) Write the structures for benzoic acid and naphthalene.

b)Give the one equation that illustrates how we are going to separate benzoic acid from a benzoic acid/naphthalene mixture.

c) What are the two solvents that are to be used to bring about the separation of the above mixture? Justify why each was chosen.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

answer: option (b) is the correct answer.

explanation:

intensive property is the physical property which does not depend on the size of system or amount of material present in system.

for example, color, density, melting point, boiling point etc are all intensive properties.

thus, we can conclude that the boiling point and color of a substance are both examples of intensive properties because they do not depend on the amount of matter in the sample.

i believe the answer is d
