Hi I need help doing this question! Thank you in advance!

Suppose that a mixture contains 1,4-dimethoxybenzene and benzoic acid. An experiment is performed in which this mixture is dissolved in diethey ether, the solution is mixed with aqueous soium hydroxide, and the aqueous layer is then separeted from the ether layer.
a) What does the aqueous layer contain? Name each chemical species, and write the structural formula of every prganic component.
b)What does the ether layer contain? Name each chemnical chemical species, and write the structural formula of every organic componenet.
