wat did u guys think of the chem regents today? i thought it was pretty fair im just hoping for above a 90.
there were some triky questions:
the one with the volume and pressure and temperature of the helium gas (it was in the short answers). wat was the answer?
wat was the answer to y the arsenic have different densities.
compare the solubility of CO2 to the temperature of the aqueous solution?
ask any questions u had trouble with :)
i put carbonic acid?? wat was the answer?
 
volume, pressure, and temperature, I forget the number. but you plug it in VP / T = VP / T. combined gas law. or were you talking abuot the gas particles? then it was the same.

arsenic has different densities becaues different structures.

as temp goes up, solubility goes down. but didn't it say co2(g) in an aqueous solution?

um what was the acid in the co2 problem? was it carbon dioxide?

dang! i think it's carbonic acid..........damn and it was on the reference table too

@iloveadam, I was thinking the same exact thing! i so shoulda checked my work!
