The answer to Lipids
Methanol, Ethanol, & 1-Propanol
1) How would you sketch these three alcohol molecules?
2) What is each of their polarity?
3) What differences might you expect in the comparative solubility of each of them in lipids? WHY?
4) If you were to add 2 drops of sheep blood to each of these alcohols (about 1/3 of a small test tube amount of each alcohol; 3M methanol, 3M ethanol, 1-propanol) what would you expect to see ROUGHLY in hemolysis time IN SECONDS?
5) Why would you get the results you did (1-propanol reacts fastest, then methanol, then ethanol). WHAT CAUSES THEM TO REACT THE WAY THEY DID?
A mixture consisting of 2.50×10!3 g of O2, 3.51×10!3 mol of N2, 4.67×1020 molecules of CO are placed in a vessel with a volume of 4.65 L at 15.4°C.
