Fri-Day 2
Chem 5 - finished bulb question.
Monday, do second bulb question with more complex numbers.
Went back to collection of gas over water, revisiting Dalton's Laws.
Monday, explain why not all gases can be collected this way, e.g. NH3.
SHOW POI KMnO4
Chem 7/8 - finished collection of gas over water; did two bulb stoich problems.
Started gas law explanations.
Finish those on Monday; Graham and Pascal on Tuesday - end of unit!
APB - fully derived acceleration direction and magnitude for uniform circular motion; then get net force towards center of arc/circle by using Newton 2.
Monday - explain whole point of derivation; v^2/r does not come from nowhere, and it is the true acceleration at each point on a circular path towards the center.
explain why things moving in a circle "feel" pushed "outward" i.e. circular case of person "feels" pushed back from acceleration direction in a car!
