(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.

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

Which statement about the stamps is correct?

How can you use chemical equations to predict the products of the reaction you can carry out?
