Oct 12 -Tuesday Code Red During Period 4
Day 22 Chem 122-We will hved a quiz on equilibrium law(expression), equilibrium constant and LeChatelier's Principa tomorrow. I did a homework check on the work from wednesday. Today we went over calculations involving Ksp. I assigned p 565 #21 to 24 Chem 121-Test on functional Groups and Organic Reactions Ch 23 and notes on reactions(delayed due to code red) We went over the start of Ch 17 on energy...terms like endo thermic, exothermic, heat, thermochemistry, temperature and the formula for q= mcdelta t p 510 #, 4 and p 510 #8 to 11 will be assigned for thursday. We will do your test on Ch 23 tomorrow as ypou only had 15 minutes befor the code red. Chem 112- Today we will do a quiz on polyatomic ions (all 11. We will go over the answers to the irregular polyatomic ion sheet that was completed for last wednesday. I will start a demo on properties of acids/bases/ionic and molecular compounds. We will go over naming molecular compounds(only started this). Diatomics, exceptions(phosphorus) and binary molecualr substances. Please do the following practise questions tonight p 266 #17 to 19 and p 273 #28 to 33. There will be another quiz on polyatomics tomorrow,I will give you information regarding the properties assignment. See the document below for details on this assignment that is due next monday.

Oct 15-Wednesday TEST Next Wednesday for Chemistry 112 on Unit 2 Chapter 9.
Day 23 Chem 122-QUIZ today on LeChatelier and Equilibrium Law Today we finished our work with Ksp and then did some more practise with Ksp. I assigned the following questions from the handout: bottom 1 to 4 and top 5 to 7. Chem 112- QUIZ today onthe same 11 polyatomic ions as yesterday.We will finish the demo on properties, then I will go over molecular naming. We will go over the formulas that you will have to study, then the diatomics and polyatomics phosphorus and sulfur. Please do sheet 5 for homework. Your test onCh 9 is on Wednesday Oct 20th.>We will go over the next things listed tomorrow as we ran out of time. We will go over 5 questions from sheet 2 on irregular polyatomics(tomorrow), 5 questions from sheet 6(tomorrow) on naming acids. I will also do a homework chekc(tomorrow). Chem 121-We did our Test on Ch 23 today. Tonight for homework do the following questions: Do p 510 #4 and #9 to 11

Oct 16-Thursday
Day 24 Chem 122- We went on to Common Ion Effect and calculations involving predicting whether or not a precipitate forms. I assigned the last two questions on the handout. p 565 #26 and 27 I also assigned p 564 19,20 and 25 for homework. Chem 121-Today we are working on specific heat and heat capacit. We went over the rest of the theory with heat flow, then the homework that was assigned. New work: We started enthalpy and reviewed phase change with exo and endothermic tied in. We went over a new table on enthalpy (17.2,17.3). delta H = nH Assigned questions were p 524 #23 and 24, p 526 #25and 26 and p 521 #21 and 22. You will be receiving a table for looking up values of specific heat(tomorrow). Chem 112-Today we will overview the properties of ionic, molecular, acid and base using our data table from the last few days. There will be a quiz on molecular tomorrow. We will go over several answers from our worksheets( tomorrow) New work: I went over hydrates today as there will be several students away with teams. I passed out a practise sheet for this. Please do #6,7,8 from this sheet. I hope to do a homework check(i will have to do this tomorrow). Test coming: Next Wednesday [|Unit 2 Practise Questionsincluding ionic multivalenthydratesandmolecularequations.doc]

Oct 17-Friday Chem 112 Test on Wednesday Oct 20 Chem 122 Test on Wednesday Oct 20
Day 25 Chem 122-Your next test is on wednesday of next week. It will cover Ch 18. You will receive a study guide for tuesday's test and we will go over the solutions to yesterday's questions. We will hopefully be able to watch the entire video on the Haber Process. We have completed the unit on ch 18 so we will start group review problems today. We will complete thes on tuesday. On monday we will start the next unit which is Ch 19. Chem 112-Quiz on molecular formulas today. This includes the list on the back of the green sheet, the diatomics and the polyatomic molecules(phosphorus, sulfur and ozone). We will do a big homework check and start a pair assignment. I will go over 5 questions from each worksheet. Assigned questions: Sheet 7 and sheet 8 from the first handout for this chapter. Please see below for helpful hints with Properties Assignment which is due tomorrow. [|Unit2TestReviewchem11.PDF]

Chemistry 121-Today you will do a pair assignment on enthalpy and heat loss or gain from the booklets. You will receive a handout that has problems for this unit on it, as well as the table that I mentioned last class.

SPECIAL NOTE TO CHEM 112 students: you will find that is good to use the formula to help decide if something is acid(hydrogen on front), Base( hydroxide on end, ammonia or ammonium), ionic(metal attached to nonmetal) or molecular(nonmetals attached to each other). [|MAJOR Properties Assignment.doc] [|Table Of Empirical Data For AcidsBasesIonicMolecular.doc] From WIKIPEDIA: The symbols in parentheses (in subscript below each species) indicate the physical state of each reactant or product. PLEASE NOTE CHEM 112 Students-->One of your classmates emailed the following questions regarding the assignment. Please read the document below with the answers to the excellent questions that the person asked. [|Good Questions regarding MAJOR ASSIGNMENT.docx] [|Good+Questions+regarding+MAJOR+ASSIGNMENT.doc]
 * **(s)** means solid --> like table salt or sucrose
 * **(l)** means liquid --> like water or hydrogen peroxide
 * **(g)** means gas --> like propane or ammonia
 * **(aq)** means aqueous solution (i.e. dissolved in water) --> like hdrochloric acid or hyponitrous acid

Practise your polyatomic ions
