Chemistry (H) Syllabus 2019 - 20 Mrs. Erin WeeksEufaula High School emweeks@eufaula.k12.ok.us

Required Material: 3-ring binder (2 inch recommended) College Rule spiral notebook for notes College Rule composition notebook (100 pages)

for vocabulary

3 Page Divider pack Pen only (traditional blue or black ink only) Scientific calculator

Course Description: Chemistry is the study of matter, its composition, structure, properties, the changes it undergoes, and the energy involved. Through notes, lectures, projects, videos, assignments, and labs, students will learn facts, formulas and principles that comprise an introduction to Chemistry and will develop critical thinking and problem solving skills in relationship to scientific thought and study. We will study dimensional analysis, atomic structure, atomic theory, electron configuration, chemical reactions, the mole, stoichiometry and more as time allows.

Grade Scale: Grades will be determined by weighted scale: Tests – 55%, Homework/Quizzes/Labs/Projects – 45%Grading Scale: A= 90-100 B=80-89 C=70-79 D-60-69 F=59 and below *If your average is a 69 or below, I encourage you to visit with me outside of class. Semester Grade = 20% Semester Test + 80% Both 9 Weeks Average

Assignments Types and Grades Vocabulary – you will be responsible for keeping a vocabulary notebook and using it to study your key

terms. You will be given vocabulary quizzes during each chapter study. Vocabulary notebooks will be collected on the day of the chapter test. If notebook is complete for that chapter, 2 extra credit points will be given to that chapter test score. It is your responsibility to prepare and learn the key terms.

Regular Studying – Students should engage in regular studying of their notes for at least 15 – 30 minutes per day as a minimum. This is considered a standing assignment.

Skills & Concept Homework – Homework Assignments are given for practicing science skills and science concepts. Grades are very rarely given for these assignments, but students are expected to do them regardless. If you choose not to do your homework, you will not be prepared for the quiz that will be over the skills and concepts. If you need more help you should make time to visit with me.

Quizzes/In-class assignments – Used to practice and strengthen students’ understanding and comprehension of learned skills and science concepts.

Chapter Tests – Used to demonstrate students overall mastery of the skills and science concepts. Answers Only: Answers only on any math will not be accepted. YOU MUST SHOW ALL WORK to receive

credit.

Make-up work/ Late Work: It is your responsibility as outlined in the student handbook to obtain and complete your make-up work. You have the amount of days absent to complete any assignments you have missed. If you are not sure what you have missed…it is your responsibility to ask me or another student and get your work. If you are not sure when your make-up work needs to be turned in…ASK!

My late work policy is as follows: 1 day 50%, any later 0%. Exceptions are rare but can occur…You must talk to me!

Laboratory: Laboratory work is an important part of science and will require a report/assignment to be completed. The laboratory is a serious and potentially dangerous place. To participate in labs, the student and parent or guardian must have read, signed, dated, and returned a safety contract. Additionally, the student must complete a safety lab, and perform 100% proficiency on a safety exam.

'Horseplay' or other unsafe or disruptive behavior will not be tolerated. Failure by any student to comply with lab rules will result in dismissal from future lab activities.

Make-Up Labs:Most labs in this course require advanced preparation and set-up and because of this lab make-up will consist of a 2-page written report over an assigned topic that will be due two days after assigned.

Missed Tests Test dates are announced at least one week before the test. All make-up tests will be a different test from the original and may include more essay/short answer type

questions. If a student knows he/she will be absent on a test day, I highly recommend that the student visit with me to

arrange a time to take the regular test early or before school on the day following the scheduled test day. If you miss a test it must be made up on the following Tuesday after school. Failure to do so will result in a zero.

(Special circumstances aside.)o If you are unable to make-up your test during that time, you must see me BEFOREHAND to

schedule a different time.

Technology Policy A Chromebook will be available for students to use in class at appropriate times , therefore, cell phones, smart watches (any brand), and any other portable/wearable technology use will not be permitted in class. These items must be turned off and stored during class. A container is provided at each desk for technology storage and it is the student’s responsibility to collect their items at the end of class. Violations of this policy will coincide with the EHS Cell Phone Policy. This includes during any coded school lockdown or drills, and other safety drills.

Expectations:1. Always show respect—to your classmates, to visitors, and to me. It makes everything run a lot smoother

and we will be able to enjoy the class so much more.2. Always be willing and ready to learn and participate—class is so much more fun when you actually want

to learn something new and are prepared to have a conversation about the topics.3. Always be on time. That means in your seat and ready to work by the time the tardy bell rings.4. Restroom usage - go before you come to class. 5. No food, candy, or drinks permitted in class. Gum will only be permitted as long as I don’t see it or hear

it.

Binders: It is important to keep up with your vocabulary, old tests, and notes for the semester. Your semester test will come from ALL the information that is taught during the semester. There will also be a few items that carry-over to next semester that will be recommended to keep. It is recommended that you use your page dividers to organize your binder into the following categories:

The Periodic Table of ElementsYou are responsible for memorizing the element names and symbols.

We will work on these 20 elements at a time and take quizzes beginning Sept 6.

Electronegativity Values

Naming CompoundsIs the first element a ___?

Does the compound include Hydrogen

and an element from the periodic table?

Yes No, It has Hydrogen and a Polyatomic Ion.

Name the compound using the Prefix

“hydro-“ and change the ending to “-ic

acid”Ex: HCl

Hydrochloric Acid

Hydrogen(This compound is an acid)

Use your polyatomic ion sheet to find the

name of the polyatomic ion in the

compound.Does it end in –ite or

–ate?

Non-Metal(except Hydrogen)

(This compound is molecular )

Look at the subscripts in the compound. Use prefixes to indicate

the amount of each atom.

Ex: N2O5

Dinitrogen PentoxideCO

Carbon Monoxide

Prefixes:1: mono 6: hexa2: di 7: hepta3: tri 8: octa4: tetra 9: nona5: penta 10: deca

Metal

Do you have a Polyatomic Ion? Hint: There will be 3 or more elements

in the compound. Or check your polyatomic ion sheet.

Yes

Name the metal, just like it is and then name the polyatomic ion. If the metal is a transition metal, include a roman numeral to indicate the change.

Ex: NaOHSodium Hydroxide

No

Name the metal, and then name the non-metal. If the metal is a transition metal, include a roman numeral to indicate the change.

Ex: NaClSodium Chloride

MnO2

Manganese (II) Oxide

Non-metals are to the right of the zig-zag line on the Periodic Table plus Hydrogen.

Metals are to the left of the zig-zag line on the Periodic Table.

-ite ending

Change the ending to –ous acid.

Ex: H2SO3

Sulfurous Acid

-ate ending

Change the ending to –ic acid.

Ex: H2SO4

Sulfuric Acid

WRITING COMPOUND FORMULASIONICS ACIDS COVALENTS

1. Write down your two ions with their charge.

2. If you see a roman numeral, it is telling you the positive charge of the metal.

3. Add subscripts in order to cancel out the charge of the ions to zero for the overall compound.

4. If you need a balancing subscript on a polyatomic ion, add parentheses around the polyatomic ion, and place the balancing subscript outside of the parentheses.

1. You will be able to pick out these compounds easily because they include the term ACID!

2. Determine which ion is in the acid based on the name.Hydro-__-ic acid = __-ide ion (nonmetal)__-ic acid = __-ate ion__-ous acid = __-ite ion

3. Balance the charge on the ion using H+1 ions at the front of the compound.

4. Add (aq) to the end of the compound, as all acids are aqueous solutions!

1. You will be able to pick out these compounds easily because they include PREFIXES!

2. Determine if the covalent is organic (one word name with –ane ending) or if it is inorganic (two word name).

3. If organic, determine the carbon # subscript from the prefix, and determine the hydrogen # subscript from presence of “cyclo”

4. If inorganic, determine subscripts from prefixes

HINT: –ATE and –ITE endings = Polyatomic Ions, but –IDE endings = Non-Metals (except OH-1 and CN-1)

POLYATOMIC IONS TO MEMORIZE!YOU MUST MEMORIZE NAME, FORMULA, AND CHARGE!
