Proteins C is a "glycoprotein", meaning that one or more sugars have been covalently attached to its side chains via post-translational modification. Describe how Concanavalin A Sepaharose could be used to isolate Protein C from the mixture. Specify how any elution steps might be carried out. Be sure to cite the reference you used to determine how "ConA Sepharose" works.

What is the % barium in an alloy if it takes 22.0 mL of 0.875M sulfuric acid solution to react with all the barium in a 7.59 g sample of the alloy
How many moles of ions are in 1.60 mol of K2SO4?
calculate the freezing point of this solution, boiling point of this solution, the vapor pressure change (from 23.76 torr at 25C) for the solution, the osmotic pressure of the solution, and the height of a column of water corresponding to this osm..
You performed this fractional distillation using an air condenser as the "fractionating" column. Explain why the distillate may have been obtained in higher purity if you would have used a fractionating column packed with glass beads.
Desribing molecular forces of C5H6O, CH2=CH-CH=CH-CH=O, THREE double bonds. We are asked to describe the bond and angle terms of this structure.
