1.) In this experiment, if the carboxylic acid is benzoic acid, how many moles of benzoic acid are present (assume an equal portion of each component)? How many moles of sodium bicarbonate are contained in 1 mL of a saturated aqueous sodium bicarbonate. Is the amount of sodium bicarbonate sufficient to react with all of the benzoic acid? molar mass of Benzoic acid =122 gm, moles of benzoic acid in 0.1385 gm= mass/molar mass= 0.1385/122= 0.001135

Draw the reaction mechanism with chemical structures in the separation of naphthalene and benzoic acid by extraction. 1g of Naphthalene/benzoic acid mixture is dissolved in 15 mL dichloromethane, transferred to a separatory funnel where 10 mL 2.5M NaOH(aq) is added. Organic and Aqueous layers are separated, and 12M HCl(aq) is added to the aqueous layer while cooling, forming a precipitate, which is vacuum filtrated. Don't understand how to draw each chemical structure!
