How you would prepare a solution of 250.0 mL of a 0.150M phosphate buffer at ph=7. (phosphoric acid pka1=2.12, pka2=7.21, pka3=12.32). What would the pH of the buffer be if 5.00mL of 1.10M HCL was added to 100mL sample of the prepared buffer.
Question: How do you imagine the graph of a three-variable system of three equations would look? How about the graph of a system of four equations in four variables?

2. Show how you would make this compound by a malonic ester synthesis or an acetoacetic acid synthesis. 4-methylhexanoic acid
3. Given the circuit in Figure A.8, write the KCL for node A. Write the three KVL equations for the three loops in the circuit. Do not solve for any of the Currents. Remember you only need 3 of the four equations to solve for the currents. v v v Figure A.8: Figure for Question #3
1. Write the acid dissociation reaction equation for Na2H2PO4. 2. Write a reaction equation showing how the buffer solution maintains pH ~ 8.0 upon addition of acid. 3. Write a reaction equation showing how the buffer solution maintains pH ~ 8.0 upon addition of a base. Buffer solution: Acid= Na2H2PO4 base Na2HPO4 4. Would you expect this buffer to be better at resisting a change in pH upon addition of acid, or upon addition of base? Why?
3) Assume that you are given a mixture of compound A and compound B, and it is your job to separate them. You are also given the following table of information. a. Describe in detail how you would separate these two compounds. Tell what solvent or solvents you would use, and explain your choice(s).

1. Write balanced chemical equations for the formation of a substance that you prepared in this experiment 2. Outline a series of chemical equations to show how your product could have been pre- pared using a Grignard reaction. Be sure to show the structures of all starting materials and intermediates. 3. Draw the structure of the product that would have been formed if benzaldehyde had been used in place of 3-pentanone in this experiment. 4. When benzaldehyde is used as...
please write clearly so i can read everything. i would be
writing on the graphs themselves so please write on the graphs
also. thank you!
10. The MS, IR, 1HNMR and 13CNMR spectra (given in that order) are provided for a compound with the given molecular formula. Calculate the unsaturation index and using the spectra, deduce the structure of the unknown molecule. For each method of analysis (IR, MS, NMR) provide all structural information gained from the spectra (Note: providing...
