Suppose a 50 year old female presents to the ER with chest pain after eating a meal consisting of a large portion of red meat, creamy sauce, and potatoes. The woman's bloodwork shows very elevated levels of serum cholesterol. It is likely she had a heart attack and will start taking statins in order to reduce her cholesterol levels. What impact do the statins have on HDL, LDL, and her triglyceride levels?

I have a question about gibbs free energy vs gibbs standard free energy.

We know that at equilibrium deltaG = 0 and Q = K, and deltaG standard is a non-zero value.
But I don't understand. If I want to see if a reaction is at equilibrium then I have to calculate the deltaG standard first, before I can calculate deltaG to see if its value is 0 or not.

And everytime I do that, the deltaG standard equals 0 under standard conditions. That dosen't makes sense comparing to the statement about that deltaG standard is a non-zero value at equilibrium.

Why is my deltaG standard always zero? The relationship between them will be: deltaG=deltaG standard at equilibrium????

It’s stated that a H2 molecule is glued together by a pair of electrons. Now you have read about molecular orbitals in homonuclear diatomic molecules. What is chemical bonding? Why are molecules hold together? (Please use general concept, without resorting to too much math.)(The answer should be no more than 800 words.)

Explain the advantages and disadvantages of open tubular vs packed columns. Why aren’t packed columns use with HPLC?

what are the three types of injections with GC and when they should be used. Explain why cold trapping and solvent trapping are used and what they are.

A 100.0 −mL buffer solution is 0.105 M in NH3 and 0.135 M in NH4Br.

A. What mass of HCl could this buffer neutralize before the pH fell below 9.00

B. If the same volume of the buffer were 0.265 M in NH3 and 0.390 M in NH4Br, what mass of HCl could be handled before the pH fell below 9.00?
