DAY 8: NOTES, POWER POINTS

***UPDATE***

The FINAL in this course will be administered after the break (11:05-1:55) on Wed., July 12th.  

NO HOMEWORK WILL BE ACCEPTED AFTER WEDNESDAY, ONLY CLASSWORK

Mr.Hatfield's 2nd-session Chemistry students took their third test today.   A class roster of 44 has now been reduced to 23 actively attending.   

The good news is that some have raised their output in the course, and now have a passing grade.  The concern is that still too many students are failing to complete work outside of class, and thus are in danger of not passing the course.   With that in mind, here are more resources to help students 'up their game' .

FIRST:   Students received notes on reaction rates and equilibrium constants in class.   A copy of the Notes can be found HERE:

NEXT:  Students will be using a third Study Guide to complete the rest of their Notes, based  on material from Chapter 19.   They can download a copy of the Power Point containing those Notes HERE:

FINALLY:  Students were given a worksheet based on the following video, shown in class.   This worksheet is due tomorrow!

You can view the video, below:

It demonstrates the centrality of water to most acid-base chemistry, and explains how to calculate equilibrium constants for acids (Ka) and bases (Kb), and how to express those as pKa's or pKb's:

DAY 7: EQUILIBRIUM

Students:  here is Paul Andersen's video on 'Equilibrium', the final video worksheet this week:



There is also a link to where you can download a PDF version of the video worksheet, HERE.

The final unit comes next week.   Students can download a copy of the Power Point containing those Notes, over the weekend HERE:

DAY 5: THERMOCHEMISTRY

Students today performed the 'Boyle's Law Lab' and the calculations based on it, which should include a pair of graphs.   This and the previous lab will be graded based on the completed Lab Report in student's Composition Books, during their . . .

TEST # 2, WHICH HAPPENS AT THE BEGINNING OF CLASS, TOMORROW!

Students are reminded that they should have all the notes on properties of gases and gas laws in their Comp Books, which they are allowed to use during the exam.

AND, speaking of Notes . . . .

Here are the Power Point Notes for the next section of this course: Thermochemistry.  

In this you will find discussions of phase changes (again!),  heat transfer, the 1st and 2nd Laws of Thermodynamics, and problems to calculate energy (q) , specific heats and enthalpies of reaction:

2nd SUMMER SESSION, DAY 2: STATES OF MATTER

 Here are the Power Point Notes from Chapters 13 (introduced today) and 14 (covered on Day 3):

Students have been given a Study Guide to facilitate quickly acquiring all of the notes.   This is an assignment and must be completed by Monday morning.  

MORE IMPORTANTLY:  All of the notes in the Study Guide must be neatly transferred into the student's Composition Book, which will not only be graded at the end of the session, but which students are allowed to use on their tests.

STUDENTS HAVE A VERY HIGH INCENTIVE TO HAVE THEIR OWN COMPOSITION BOOK AND THEIR OWN CALCULATOR.

SUMMER SCHOOL, DAY 10: NOTES, VIDEOS

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.

Students, here is the video shown in class, in which Paul Andersen demonstrates limiting reactant and percent yield problems:




The worksheet based on this video is available as a PDF file HERE.


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.

SUMMER SCHOOL DAY 9: STOICHIOMETRY

Students:  HERE is the second group of Power Point Notes for your Unit 3 test on Monday:

Student should use this video to complete a worksheet given in class, which is also available online HERE.

SUMMER SCHOOL, DAY 6: ELECTRON CONFIGURATION

Students, here is the Power Point for the second group of notes,on electron configuration, orbitals, models of the atom, and rules for electrons:

Students should use this along with the previous section of Notes to complete their Study Guide for tomorrow's test, and along the way make sure that everything in the Study Guide does, in fact, appear in the notes in their Composition Book.

SUMMER SCHOOL, DAY 5: PROPERTIES OF MATTER

Students: here are the Power Point Notes that covers material from Chapters 2 and 6.   

Students will be provided a second Power Point tomorrow covering material from Chapter 5, in order to complete their Study Guide ("Properties of Matter") that includes all of the notes for Wednesday's test.

SUMMER SCHOOL, 1st SESSION: FIRST DAY

The first set of Notes for Mr. Hatfield's Summer School Chemistry Class are now available on-line, here:

The topics of the notes include the relation of chemistry to mathematics and other sciences, what makes chemistry distinctive in terms of its content and practice, the nature of science, scientific method ("O.H.E.C.K."), atomic theory and the periodic table.

Students should download the Power Point Notes to make sure that their notes are complete, as from time to time their composition books containing their notes will be inspected and graded.

Below is an outline of the 11-day session:

POWER POINT: NUCLEAR CHEMISTRY

Students:

This is the FINAL set of Notes for the Spring semester!   The end is near, congratulations!

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.

POWER POINT: MAPPING STOICHIOMETRY

Students, HERE is the brief Power Point Notes given in class which introduces the technique of 'mapping the equation':

This technique is complimentary to the fractional setups which we have been practicing for weeks, setups that allow chemists to convert units via cancellation:

Mapping the equation is very helpful in solving more complex, real-world problems in which the order of operations is important:

In these sort of problems, you should map the equation FIRST, then use the map as clues on how to set up the order of your fractional terms.  

Considering the mapped equation above, let's imagine that we are given 72 grams of hydrogen gas (H2), and we want to know how many grams of ammonia (NH3) can be produced in this reaction . . . .

The map tells us that after we write down the given amount as the first term, the second term should use the molar mass of hydrogen gas (2.02 g/mol), expressing it as a fractional term.   The third term, the mole ratio, we get from the balanced equation:  it tells us that for 3 moles of  on the reactant side, we should have 2 moles of  on the product side.   Finally, to convert from moles to grams, we use another molar mass, the molar mass of ammonia (17.04 g/mol ).

POWER POINT: STOICHIOMETRY

At the end of today's lesson, they were given a Homework assignment, "Calculations With Moles." That item is available HERE.

STUDY HALL will occur the next two weeks at lunch (Tuesday and Thursday), and after-school on Wednesday.   Students who have been assigned STUDY HALL must attend, or they will be treated as defiant.
