Tues-Day 2
Physics - we looked at the derivation of the work/energy and power equations in terms of potential difference (V), current (I), resistance (R), and time (t). We then looked at problems involving P and W/Energy in Circuits 1 and 2.
We reviewed how to calculate the number of electrons passing a point in a circuit in a given amount of time (multiply the total charge in Coulombs by 6.25 x 10^18 electrons per Coulomb).
We reviewed electric circuit diagrams.
We then expanded these diagrams by drawing in multiple resistors consecutively connected "in series".
The equivalent or total resistance of the circuit is then simply the SUM of the resistances of the individual resistors in the series circuit.
With that we can get the constant and uniform current throughout the circuit, using Ohm's Law.
The descriptive chem quizzes will be returned tomorrow- grades from that quiz are on Blackboard.

AP Chem - we finished the formal method of obtaining rate law exponents from the data table, solving for k, and then applying the rate law to another trial at the same temperature but having different reactant concentrations.
We then started on the TIME-dependent equations of kinetics by looking at 0th order reactions, and 1st order reactions.The descriptive chem quizzes will be returned tomorrow- grades from that quiz are on Blackboard.
