SYLLABUS, UNIT 6: THERMOCHEMISTRY

Students: Please below find your latest Syllabus.  

This will be a short unit (only 15 instructional days), with a total of three labs,two of which will be COMBINED in one 'super two-day lab'.  

Note also that students in need of remedial support will be assigned Saturday School on Saturday, Feb. 23rd.  Failure to attend Saturday School as assigned without a parent contact will be treated as defiance.

VIDEO: GASES

Paul Anderson helps us out again.   This video has a great set of demonstrations using a set of interactive animations.   Students are expected to complete a worksheet based on this video:







 The simulation that Mr. Anderson uses in the video can be accessed online, at the University of Colorado, HERE:

VIDEO: TEMPERATURE

As we begin our notes on the 'Kinetic Theory of Gases', it is important to realize that the random, dynamic motion of a very large set of tiny (sub-MICROSCOPIC) particles produces the phenomena we can observe at our own, relatively large (MACROSCOPIC) scale, like pressure and temperature.

Paul Anderson demonstrates this in the following video.  Students will receive an accompanying worksheet based upon it!

SPRING 2019: NEW UNIT 5 SYLLABUS

WELCOME BACK!

Students in Mr. Hatfield's Chemistry classes will be spending much of the first week of the Spring 2019 semester  completing handouts which review math routines taught and rehearsed in the Fall semester.  

On ATLAS, these assignments will display as four separate classwork assignments: Molar Mass, Two-Step Problems, Three-Step Problems and Stoichiometry 1.   Each is worth 20 points, but they are shown on the Syllabus below as a single (80-point) assignment:


Students should've also begun answering the Section Assessment Questions from Chapter 13, and beginning on Tuesday of the second week, begun to absorb new material on kinetic molecular theory and gas laws.

POWER POINT: STOICHIOMETRY OF FLUIDS

Students: HERE are the Power Point Notes on 'Stoichiometry of Fluids' given in the first two weeks of Unit 4, the final unit of the Fall semester in Mr. Hatfield's Chemistry classes.   



This section of notes covers problems having to do with molar volumes of gases, limiting reactants and percent yield, molar concentrations and other properties of solutions.   A Study Guide based on these notes is available HERE in PDF form.

VIDEO: SOLUTIONS

Students can watch Paul Andersen's discussion of solutions and their properties as many times as needed here, on-line, in the video embedded below:




Students can also access the PDF version of the worksheet given in class, based on this video, HERE.
