What is one way to turn an alkene or an alkyne into an alkane?
Hydrogen and palladium on carbon (H2, Pd-C) would reduce either of those completely!
Two acids are in equilibrium with each other. One has a pKa of 10, while the other has a pKa of 20. Which acid will have the highest concentration at equilibrium?
Equilibrium lies in the direction of the higher pKa, which is also the weaker acid. In this case, the acid with a pKa of 20 will have the higher concentration.
Describe the structure of DNA (as specific as possible) and explain why it is significant.
DNA is found in the nucleus as a double stranded helix. Each strand is made of nucleotides (A, T, C, and G) attached to a backbone (deoxyribose and phosphate). The double strand means that each side can be copied without getting rid of the original material!
