was the answer to the last question a half

Our school said it was a typo, and that you only had to find the find the volume of water in the tunnel. so all we had to do was multiply the cross sectional area of segment by the height.

Re: CSSA Chemistry 2011 I did that exactly except, i though 1L equaled 1 M^3, i got like 35 %. ARGHHHHHH Thhe calcs were pretty straaight forward overall, just stuffed up the dry cell question.

A chemist wanted to find the percentage of caco3 in 2g of limewater. He added 100 ml of 0.905 mol/l HCL which was more than enough to react with with the calcium carbaonate. After the bubbling had ceased, the resulting solution was titrated with sodium carbonate solution. 30.45 ml of 1.01 mol/l...

so the the one which is all used up, how come in back titrations and some Ph questions you use the excees value of mols?

i have a questrion, when a calc involves limting reagants, you use inital reacting excess do you use the amount of moles in exess for the rest of the calulation or the amoiunt of moles reacted

LMAO, Im retarded

u der

wait

cl- hso4- h20 SO42- ch3coo- hco3- nh3 co3 2- oh- dosnt have one

i did ti
