1 lb = _______ kg - 0.454 5 steps of creating a Lewis structure - 1. calculate total number of valence electrons available 2. determine which will be the central atom 3. arrange atoms symmetrically around the central atom 4. place bonds/electrons around the atoms until the octet rule is satisfied for each atom, using double or triple bonds if necessary 5. show any charges on the molecule by using brackets and writing the charge in the top right corner outside the brackets acid + base --&...

how are H bonds formed in beta sheets? Correct Answer-- between strands - H-bonds are lateral why do proteins fold if it would lower entropy? Correct Answer-- the hydrophobic effect - deltaH --> all of the interactions happening w/in the protein are favorable + overcome the unfavorable entropy of folding what types of interactions stabilize 3* structures? Correct Answer-- H-bonds - ion pair / salt bridges - van der Waals interactions: weak electrostatic interactions b/t induced dipo...
