chem 111 mole project is still due on friday Chem 112- 1-You will have a quiz on the names formulas and states for the molecular compounds 2-We are now going to deal with the last family the ionic hydrates. They are ionic but have water molecules attached. From the long sheet you did 6 and 7 in class on naming and writing the formulas for hydrates. Do #8 on the sheet tonight and the hydrate handout aS WELL 3-We overviewed properties of compounds/molecule/ionic/acids/bases.(your assignment was due today) Sheet 7 and 8 from the pink handout should be completed for Thursday 4. we worked on group work Please do the ques from your text for Thursday(good practice for test) 5-hwkp 273 29-32, p 281 57 to 61 and p 279 39 to 41 __Chem 111- Quiz again today on molecules__ 1- You had a quiz on molecules and polyatomic/diatomic molecules today 2-We are now going to deal with the last family the ionic hydrates. They are ionic but have water molecules attached. From the long sheet you did 6 and 7, 8 on naming and writing the formulas for hydrates. You also received a hydrate sheet to do. 3-We overviewed properties of compounds/molecule/ionic/acids/bases.(assignment due today) Sheet 7 and 8 from the pink handout should be completed for thursday 4-We worked on group work. SEE BELOW

Chem 122-Test on Ch 18 now on Thursday instead of wednesday Day 27- 1-We went over an assortment of homework questions...10 on activation energy, 8 on Keq, 3 on Ksp and 4 on common ion. 2-You then worked on group review problems. Homework: FOR FRIDAY Tuesday and Thursday NIGHT TO PASS IN ON Friday mar 20>>>You will be doing some theory work from 19.1 for homework on your own for Friday. Please make up at least one page of detailed notes and type a page of ten questions that cover the theory from 19.1(they cannot be identical to the ones in the text on p 593), next write the answers on the back of the page. On p 593 Do #1 to 8. This will be passed in on Friday Mar 20 for marks Test help .answers to 18.1/18.2/18.5 on handout and 18.3 Solubility Equilibrium Ksp Practise Problems 1-7
