I really need help with this question...I have no idea where to start! But I do know that it has something to do with activity coefficients.

when the water level is higher inside and outside the flask, is the gas pressure in the flask higher than or lower than or the same as the atmospheric pressure? how could failure to equalize the water levels inside and outside the flask before clamping the rubber tubing in the stopper assemble affect results?

I am new to this school, and while going through my chemical closet, I found a plastic sandwich bag with a shiny, purple solid inside. It was broken into small pieces. All I know about the material thus far is that it dissolves in water and turns the solution a dark pink color. Any information on where I could look up the physical properties of certain elements or chemicals would be greatly appreciated. Thank you.

It's with both the quantitative analysis (with titrations and stuff like that) and qualitative analysis (finding out what a certain given chemical is by doing the tests on the question paper).

I hardly ever get the right amount of stuff in the titrations and my qualitative analysis is even worse. An utter mess. I get this weird precipitate when it's not supposed to be there and the colours are really odd. The last time I did one, my precipitate was this unameable dark brownish (?) colour.

Desperately seeking a little help. What's going wrong?! (Even the teacher is mystified when I ask.)

Cardiac arrest occurs when the heart stops and blood circulation is halted, but cellular reactions continue. When this occurs, doctors often inject sodium bicarbonate solution, NaHCO3, which contains the base HCO3, directly into the heart muscle even before restarting the heart.

a) what effect would cardiac arrest have on blood pH? why?

b) how would the injection counteract this effect?
