Tues-Day 1
Bio 3/6 - we discussed autotrophic and heterotrophic nutrition, the three distinct processes involved in nutrition (ingestion, digestion, egestion), and the two types of cellular digestion (intra and extra).
AP Chem - we discussed and applied the various formulas for colligative properties of solutions: freezing point depression, boiling point elevation, and osmotic pressure elevation.
We re-arranged the formulas so that we can calculate the most common/practical quantity inferred by these properties: the molar mass of an unknown solute.
We looked at the similarities and differences between Dalton's Laws and Raoult's Law and saw that, typically, both laws are used in problems involving vapor pressure calculations.
