POWER POINT: PRESSURE AND TEMPERATURE CONVERSIONS

Students:  here is the (brief) Power Point containing information about the physical basis of temperature and pressure in the metric system, and how to convert units related to the same:







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 2018 SEMESTER BEGINS!

WELCOME BACK!

Students in Mr. Hatfield's Chemistry classes will be spending much of the first week of the Spring 2018 semester completing a four-part packet of handouts which reviews math routines taught and rehearsed in the Fall semester.  

On ATLAS, this packet 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.

STUDY SESSION FOR FINAL

As a reminder, students, Mr. Hatfield is having a Study Session after-school today (Tuesday, Dec. 12th), in which we will review ALL the types of calculations likely to appear on the Final.

First come, first served.

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.

SYLLABUS, UNIT 4

This is the FINAL Unit of the Fall 2017 semester in Mr. Hatfield's Chemistry classes.  Major topics include:  reviewing past lessons on stoichiometry, applying stoichiometric principles to new problems involving fluids (liquids and gases) and introducing the rate of reactions.
