Tues-Day 1
AP Chem - we reviewed the percent composition to empirical formula to molecular formula problem, explaining the rationale for each step.
We then did a similar problem involving a three-element compound, and also a percent composition to empirical formula of a hydrated salt problem.
We then tried the most involved problem so far: the gravimetric analysis of a compound via precipitation in which we determined the identity of an unknown cation.
Bio - we began our unit on Biochemistry, the structure and function of the major types of compounds that make up all of the different structures in an organism.
We looked at the general classification of inorganic compounds (do NOT contain BOTH C and H) and organic compounds (contain BOTH C and H).
Water, oxygen, and carbon dioxide are three major inorganic molecules in biochemical reactions.
We introduced the four major types of biological organic molecules: carbohydrates, lipids, proteins, and nucleic acids.
