If you finish early you will work on the prelab....which has to be completely done for Wednesday in order to gain entrance to the lab

Chem 111- 1- I quickly pointed out molar mass to you 2-Today we worked on balancing chemical equations. Please do Sheet 4 A and B and copy sheet 18 into your notebook Homework :Text p 315 #48,49, 53c and 54 c You received a handout of practice with balancing equations-try these over the next few days(It is very important to figure each equation out on your own so that you become proficient at balancing) 3- We worked with calculations involving the mole. We worked with n=m/M You received some practise questions. Please do A #1 A-E from the pink handout. Chem 111-Mol project part 1 is due today

Tuesday Mar 29 __ Chem 122 __ 1- Labs will begin tomorrow. Remember no contact lenses, nylons or open toed shoes tomorrow 2-We reviewed Ka and looked at the answer to 7 from the side of the practise sheet. I also had you do sheet one( 1 to 3) that gave you some more practise with calcuator(number crunching ) Do p 611 24 to 27 for hwk during labs 3-I introduced you to Kb and assigned 6, 9 to 12 from the side of the practise sheet. 4- PRELAB-please have this ready to begin labs tomorrow. This must be submitted to start labs. Chem 111-

1- We worked with calculations involving the mole. We worked with n=m/M You received some practise questions. Please do A #1 A-E from the handout. 2-We worked with the mole formula today m-=n X M Please do #2 A to E. 3-You also did some more work with balancing equations. Do A B and C from sheet 4. Please do this in your notebook P:Text p 315 #48,49, 53c and 54 c

Wednesday Mar 30

__Chem 122__-Day 1 labs
