Tues-Day 2
Physics - took the multiple choice part of our projectile motion unit exam; tomorrow, we will have the written-response part of the exam during the first period of our double.
AP Chem- The hydrated salt lab write-up is due on Friday. Make sure that all work is explicitly shown in detail for all calculations, and that all answers/explanations are drawn/written in complete sentences in explicit detail.
We continued the gas laws solving for the molar mass of a substance given its temperature, pressure, volume, and mass (while it is in the gas phase).
We then discussed two versions of Dalton's Law that show pressure and mole relationships in a mixture of gases.
We aslo did a Dalton's Law of Partial Pressure/Ideal Gas Law problem involving a gas collected over water, a process that automatically introduces water vapor as one of the gases contributing to the total pressure.
See Blackboard for more practice with this.
