C5H5N, and 0.350 moles/l in pyridinium chloride, C5H5NHCl you are given a kb value of 1.7 x 10^-4 for pyridine find the ph of this solution using this kb value
Lipitor blocks production of chlosterl in the liver. In addition to this reduction of the serum level of cholsterol, HDL acts to remove LDL from the bloodstream. How might this occur?
The carbohydrate glyceraldehyde is shown below in several different Fischer projections. Sort the structures according to whether the Fischer projection represents glyceraldehyde
Consider the four equations of states(EOS) below describing PVT behavior of gases. Let a and b be constants. EOSI : PV = RT EOSII: (P-a)V = RT EOSIII: P(V-b) = RT EOSIV: P = RT/(V-b) - a/V (a) Prove for EOSI that both U and H are functions of T on..
