Homework:
29, 32, 33
1/2 test next class (it counts in the test category, but it counts 1/2 the amount of the thermo/equilibrium tests)
Today was about practicing. We reviewed the gas laws homework, did some extra practice on pages 5 and 6, and then took a practice quiz (last 3 questions on page 6, 12 minutes).
Homework: 29, 32, 33 1/2 test next class (it counts in the test category, but it counts 1/2 the amount of the thermo/equilibrium tests) The final exam will be 90 minutes long and have 46 multiple choice questions on it. The review below is not due but may help you as you prepare for your year-long cumulative exam. I suggest taking each section and answering any question that you don't remember the answer to.
We finished the gas laws; we know about the combined gas law and the ideal gas law.
Homework: page 5 EVENS We did thermochemistry test corrections and then did a socrative as a review for the test next class.
Mrs. Lozano will leave the socrative active throughout the week. Her room number is: LozanoE122. Homework: packet problems 13,16,24,30,36 The test has been moved to Thursday/Friday. Check your answers to the Review in a different color (answers start on page 3)
Le chat answers on page 10
We were introduced to equilibrium. Homework: 2-10 EVENS and 5
We took the thermochemistry test. We were introduced to a new type of reaction - equilibrium,
We started a 'bean counting' activity. Homework: FINISH the bean activity at home. Review for test Here are some of the resources you missed. Please note that missing a review does not mean that you won't be expected to take the test next class. If you think you shouldn't take the test, contact your teacher before the test day to discuss this matter. Homework: complete review questions 1-4 and then correct your work (in a different colored pen) using the answer key below Practice Quiz with Answer key on page 2 (give yourself 15 minutes)
Review - this is a new review; send Mrs. Lozano an edmodo if you think one of the answers is wrong...
We learned how to mathematically apply the law of conservation of energy. Then, we looked at reaction coordinate diagrams and used enthalpy to complete a practice problem.
Homework: 5,6,10 quiz next class after we go over homework questions We took the stoichiometry test. Homework: complete the 'pre-lab' on a blank sheet of notebook paper
Today in class we spent time reviewing for the test next class. First we reviewed homework, then we worked on a review problem, we took a practice quiz and then worked on a stations review. (review can be found below with answers) H.W. Pg 6-10 # 3,7,12 & 13
We got to see what happens in a chemical reaction when the limiting reactant runs out (the reaction stops). We learned about percent yield and worked some practice problems,
Homework: from page 6-10 work #9-10 (we updated the questions slightly); see the updated versions below: 9.Sulfuric acid reacts with aluminum hydroxide by double replacement. 3H2SO4 + 2Al(OH)3 ® Al2(SO4)3 + 6H2O If 750.0 mL of 3.00 M sulfuric acid react with 900.0 mL of a 2.70 M of aluminum hydroxide: a.)What is the limiting reactant? b.)What is the theoretical yield of aluminum sulfate in grams? c.)How much excess, in grams, remains? d.)How many grams of aluminum sulfate would be made if the reaction only has a 65.4% yield? 10.The compound SF6 is made by burning sulfur in an atmosphere of fluorine. The balanced equation is: S8(s) + 24 F2 (g) ® 8SF6(g) In a reaction between 80.0 grams of octasulfur and 160.0 grams of fluorine: a.)Which is the limiting reactant? b.)How many liters of SF6 could be produced at STP, assuming 85% yield? c.) How many grams of the excess reagent would be left over? (Ignore the % yield.) Egg drop lab!
We also learned about calculating limiting and excess reactants. Homework 1) finish the lab (make sure to answer the questions under the calculations section and the post-lab questions) - x3 quiz grade 2) complete page 7 #4 We corrected the reaction test to earn 1/2 credit back. We learned about converting between volume and moles using molarity for solutions and the molar volume of gases for gases. We began thinking about the egg drop lab (use chemicals to inflate a bag such that an egg won't break when it falls on the bag). Homework: 1) have a teammate bring 1-2 eggs 2) page 4 #5-8 3) complete a 'pre-lab' by writing the reaction and coming up with the basics of a procedure (the lab is found below)
We took the reactions test and then learned about using coefficients as a mole-to-mole ratio (stoichiometry). See attached notes.
Homework: pg 3 #1-4 We learned about synthesis and then reviewed for the test. Homework - this homework will be submitted to your teacher 1) complete all problems in the mixed review (powerpoint below); there are missing question numbers (don't worry about the missing numbers) 2) CORRECT your answers using a different colored pen/pencil (answer key below) You can also work the review on page 11. Answers posted below.
We reviewed the homework and then took a quiz on combustion, SR, redox, and decomp. Then we learned about using the solubility rules to create solids in double displacement reactions. Finally, we did a short lab where we made 5 solids and 1 gas.
Homework: Complete the lab. Directions are at the bottom of page 6 in your packet. Hollick students are still on a different schedule.
Merino/Lozano We discussed the 4 types of single replacement reactions and the 9 types of decomposition reactions (we made a foldable). Homework 1. fix your lab (if needed) 2. pg 5 3. pg 10 4. quiz over combustion, single replacement, redox, and decomposition Hollick's students had a different assignment.
Merino/Lozano We learned how to identify a redox reaction and then did a lab to determine the activity series for a list of 5 metals (tin, copper, silver, zinc, magnesium). Homework: complete the lab (directions on page 4 of the packet; pay careful attention to the notes written in the equation section) *this lab is a quiz grade We took our nomenclature test and did an activity (different for different class periods).
Homework: whatever your teacher assigned to your class |
