Merino and Hollick's classes
Today in class we reviewed Molarity and Solubility and took a quiz over Molarity. Next we learned about pH and acids and bases. we also learned how to use the pH equations. H.W. 1) Back of half sheet 2) Study for test (test is Thursday/Friday) Merino and Hollick's classes: Ms Lozano did something different since she has a sub.
Today in class we took a nomenclature quiz. The we practiced molar conversions. We also learned about solubility and solubility curves. HW 1. finish page 4. (make sure you do #5 at the top) 2. Quiz next class over Molarity conversions Today in class we learned calculations for dilutions. Then we did the solutions lab. H.W. 1) Nomenclature Quiz next class pg 7 Ionic: #1-5, 11-15 & Ionic Exceptions: #21-25, 31-35 Acids: All (#61-77) 2) Finish lab
We learned about molarity and how to make a solution and perform a dilution. Homework: 1.) Page 2 EVENS 2.) Download the lab document below and complete the prelab instructions.
We took a test and then learned about putting ions together to name and write formulas for ionic compounds.
Homework: Naming Ionic Compounds worksheet We took our last ion quiz, reviewed the mole quiz and homework, and then practiced to prepare for the test next class (over the mole packet and ions). We used socrative, a website/app. If you want to do the socrative, Mrs. Lozano will leave it open until the test. Get the socrative app or go to socrative.com and use room code LOZANOE122. Homework: 1) study ions as they were be ON THE TEST 2) answer the 6 problems in the document below and then check your work with the answer key provided
Due to the science fair awards ceremony, teachers are in slightly different places. Please check with a classmate to confirm that this is your homework assignment.
We discussed oxyanions and hydrates. Then, we completed a lab and turned it in during class. HW is from the packet 15-18 43,45,48,57 We took ion quiz #2! We discussed creating mole-to-mole conversion factors and how to do conversions when the chemical species don't match (3 step process).
Homework: 1. Finish How Big is Your Mouth Lab (questions in packet) 2. Sign up for Bowie Science Fair (weebly) & bring your pink sheet/donations by Thursday 3. Mole quiz next class We discussed molar mass, particle type, and calculations involving the mole. We gathered data to see who could hold the most water molecules in their mouth and will do calculations in class next time.
Homework: 1. Sign up for science fair on the science fair sign up tab (optional/there is an incentive....) 2. particle type practice on page 2 3. pages2/3 #1-9 4. bring science fair donations 5. ion quiz next class Opportunities to give back to the community. Volunteer to be a science fair judge for elementary students at Cowan, Mills, and/or Clayton. Get information from your teacher. We took an ion quiz (these will be happening regularly). We learned about significant figures and did a prediction/calculation activity with popcorn kernels. Some classes got into molar mass and particle types, as well.
Homework is page 2 & BRING A CUP/WATER BOTTLE Memorize this list. Be prepared for a quiz the day we return from break. I will give you the name or the formula. You must give me the charge and the name/formula. Be prepared to go both ways (name to formula and formula to name). Spelling DOES count so use your periodic table to help with fluoride, chloride, and chromate (to name a few commonly missed names). Here's a quizlet to help you: https://quizlet.com/_1ubwod A little bit every day is the best way to memorize this list.
We took notes on intermolecular forces (copy of NOTES at bottom of this post) and used our knowledge of inter- and intramolcular forces to answer lab questions (given below). Then, we began a final exam station review. HW: 1. study for a quiz next class on inter/intramolecular forces 2. finish your lab by answering the lab questions below: LAB QUESTIONS 1.Not all attractions are created equal. Explain the key factor that affects the strength of dipole-dipole interactions. 2.Which are stronger, intermolecular forces or intramolecular forces? Cite evidence from your lab data. 3.In determining the strength of the intermolecular forces, it is important to consider the net forces present (all the types of forces present and their relative strengths). a.State the types of intermolecular forces present in water and in paraffin wax. b.Explain why water, despite having hydrogen bonding, is a liquid at room temperature whereas wax is a solid. 4. Consider the halogens at room temperature. Explain why fluorine (F2) and chlorine (Cl2) are gases whereas bromine (Br2) is a liquid and iodine (I2) is a solid. (Start by listing the types of IMFs for each substance.)
90 minutes, 50 multiple choice questions
We are learning about intermolecular forces and intramolecular forces.
Homework: complete all pages of the POGIL /We reviewed for our test on WednesdayThursday. Missing today does not necessarily mean you will be skipping the test since no new information was learned. Please talk to your teacher in advance or come prepared to take the test.
We spend much of this class practicing & reviewing lewis structures, shapes, angles, hybridization, polarity. Homework: Science fair!
We finished building the shapes with play-dough (while filling out the chart on pages 7 and 8). We discussed how to determine if a molecule is polar or nonpolar.
Homework: Complete the following for the 6 molecules listed on the top of page 9 -lewis strcutres with formal charge calculations shown -identify the shape and bond angles -determine if the molecule would be polar or nonpolar We reviewed our homework and then took a quiz on nomenclature and lewis structures. Then, we practiced doing lewis structures that have charges (pg 3 #3b). Finally, we began to notice that lewis structures allow us to determine what shape a molecule has (and its bond angles).
Homework: 1) bring 15 blank notecards 2) finish the first 4 columns on pages 7 and 8 (do the lewis structures, bonding domains, nonbonding domains, and steric number) 3) begin working on your board (due after Thanksgiving break) There is some variation due to various teachers being out this week. Be sure to listen carefully to your teacher.
A-day students: your abstract and the pink sheet is due today! We reviewed and practiced with lewis structures and began working on 3D shapes (using pg 5 & 6). Homework: A-day students: -pg 2 #3 &4 -pg 4 #4a-f -quiz Monday on covalent nomenclature and lewis structures B-day students: -update your abstract - due Friday -get pink sheet signed |
