State chemical equations for the formation of the following Fischer esterification products- ethyl acetate, phenyl propanoate, benzyl acetate, isopentyl butanoate, methyl o-aminobenzoate.
a 5.96-g sample of homogentisic acid a weak organic acid having ka4.0 x 10-5 is dissolved in 35.0 ml of water and its
As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 75.0 atm, what was the volume of the sample? Assume that the temperature was held constant.
A 6.38 mg sample of potassium hydrogen phthalate was dissolved in 50 mL of water and to use as a standardizing aging. If 36.5 mL of NaOH was required to reach the end point, what is the concentration of the solution in uM

Give all structural and geometric isomers for the monobromination of propylcyclopentane. Number the different isomers. Draw geometric isomers next to each other and label cis/trans.
Draw a Lewis structure that obeys the octet rule for each of the following anions. (Assign lone pairs, radical electrons, and atomic charges where appropriate.)
In the following procedure, we are performing an extraction with ethyl acetate. What compounds are we separating from our product? Procedure
A gaseous mixture contains 420.0 Torr of H2(g), 391.3 Torr of N2(g), and 79.5 Torr of Ar(g). Calculate the mole fraction, X, of each of these gases.
How many milliliters of 0.121 M H2SO4 are needed to neutralize 0.220g of NaOH? If 42.5mL of 0.220 M HCl solution is needed to neutralize a solution of Ca(OH)2, how many grams of Ca(OH)2 must be in the solution?
This is a reaction between Tetrabutyl bromide as well as NaOH- with an indicator of .1% bromo-phenol blue. Explain the reaction is timed as well as whenever the solution changes from blue to yellow the timer were stopped.
