THE BEHAVIOR OF GASES
We are done with STOICHIOMETRY. If you haven't handed in the Assignment, please get it to me asap. We are finishing the year with ONE final unit on Gas Pressure.
GENERAL CHEMISTRY STUDENTS ONLY
I would like you to watch TWO videos After you've watched them, you have one FINAL assignment to complete. It will count as an EXAM grade. I will post it by tomorrow.
Here are the two videos, just click on the link:
Here is the test: TEST
HONORS CHEMISTRY STUDENT ONLY
Please watch these four videos, and complete th etest. It is highly encouraged that you watch them twice!
Video 1 GAS PRESSURE-THE BASICS
Video 2 MEASURING PRESSURE
Video 3 GAS PRESSURE CONVERSIONS (Problems 3,4,5)
Video 4 IDEAL GAS LAW IDEAL
Video 5 GAS LAW (PROBLEMS #6-10)
Honors Students: Here is your Stoichiometry Worksheet, due 5/11/20 Click right here!
General Chem Students: Here is yout Stoichiometry Worksheet, due 5/11/20 GC click here!
1. STOICHIOMETRY: The study of quantitative relationships between the amounts of REACTANTS and PRODUCTS formed in a chemical reaction.
2. It is based on: The Law of Conservation of Mass.
3. Stoichiometry is from two Greek words that mean "measure the elements."
Make sure you know this definition, what it is based on, and the Greek meaning!
Please watch this video I made (it is also on Google Classroom): Complete the Challenge Question. Don't worry if you don't get it right; I'm just looking for you try.
REGULAR CHEMISTRY STUDENTS: Molar Mass Worksheet #2: there are still students who have not turned this in. Please do so asap.
REVIEW FOR CH. 9: These are 7 problems for which I provide you THE ANSWER. You must illustrate WHY this is the correct answer.
CH. 9 TEST: I will be posing it tomorrow. You will have a week to hand it in. NOTE: ANY PROBLEM that doesn't show work will be marked "incorrect."
Converting Mass to Moles
Converting Moles to Mass
Converting grams to atoms
Converting atoms to grams
One last thing: When you are logging into Google classroom, it must be from your SCHOOL EMAIL ACCOUNT.

I will be available to talk by phone to either students or parents every day, from 9-10 am and 2-3 pm. My phone number is (352) 535-0599. Please leave a message if I do not pick up. Include your name, phone number and the best time to call you back.
2019-2020 Chemistry Syllabus (link to Word Document)
Chemistry is the study of matter and its changes. In this course, we will explore atoms, properties of matter, changes in matter, bonding, chemical equations, types of reactions, the Periodic Table, writing chemical formulas, naming chemical compounds, electromagnetic radiation, gas laws and reaction rates.
Chemistry is all around us. We use chemicals, wear chemicals, and eat chemicals. This course will enable us to explain why salt disappears in water, why iron rusts, why solutions change color and why certain reactions happen faster than others.
You will be listening to lectures, (and taking notes), working in a laboratory, collaborating with your peers in small groups, and demonstrating what you have learned in a variety of ways, including quizzes, tests, lab reports, class projects, and class discussions.
Materials Needed for Class:
A folder with pockets
A calculator (I have a class set if you need to use one.)
1. Come to class on time
2. Come to class prepared (with pencil, notebook & folder)
3. No eating food of any kind in class.
4. Each student may have ONE (1) beverage, as long as it is 16 oz or less, and has a cover (lid, cap, etc.)
5. No cell phone use of any kind. This includes ear phones, ear buds, Bluetooth, etc. This will be strictly enforced. Do NOT enter class with a cell phone out. You will not be permitted to enter class until cell phones and all listening devices (ear buds, etc) have been put away.
6. Be respectful of others at all times.
10% Class participation: come prepared to class, try to answer questions, engage in class discussions, do not sleep during class, do not disrupt others from learning
50% Exams & Quizzes
40% Lab Reports and Class Projects
As your teacher, I will decide where you sit. Your assigned seat can be changed at any time to better facilitate learning in the classroom. If you wear glasses, make sure you wear them to class so that you can see the board. If you are asked to move your seat at any time, please do so quietly and without argument. Failure to do so will result in a referral to discipline and removal from the classroom. If you are unhappy with your seat, please let me know and I will make the appropriate accommodations.
If you need to use the bathroom, please raise your hand and ask politely to leave the classroom Only one person at a time may use the restroom. You must sign out (name & time), bring the “RESTROOM” pass with you, and upon your return, sign back in (time.) A bathroom pass may only be used to go the bathroom. You may NOT go to a vending machine, guidance, the office, etc. During an exam, you must leave your cell phone at the teacher’s desk.
Laboratory activities will take place in our classroom, and on occasion, in a different lab. You must sign the Safety Agreement to work in the lab. On a day in which we are working in the lab, all long hair must be tied back, and no open toed shoes are allowed. You are expected to conduct yourself in a respectful manner in the laboratory at all times. Any display of unsafe behavior will result in immediate removal from class and possible suspension from any future labs for the remainder of the year.
Any student who is absent must take responsibility to see me about missing/make up work.
