I need to find the percent yield (actual/theoretical x 100) of copper in an experiment:

i got 7.95 grams of copper sulfate in the beginning
copper was separated from the copper sulfate at the end and had a mass of 2.66

so how would i find the theoretical data? like how would i know how much of the copper sulfate was supposed to be copper?

i need to find the percent yield of copper. if you are good at chemistry, PLEASE HELP

I've been on Wellbutrin for about two weeks now, and I'm at a 150mg dose at the moment. (My doctor prescribed it for my ADD.) The problem is, I feel like it's not helping me at all. I've become more antisocial, I've started snapping more at my parents, and my ability to concentrate has become worse. (It was bad enough to begin with...) The snapping has to be the worst though... I suddenly feel angry when my parents bring up something I don't really want to talk about, and afterwards I feel bad. It's almost like I don't know what the heck came over me. Also, I feel more depressed than before... is that even possible, for an antidepressant to make you feel depressed?
Well, anyway, I need some advice... Is this normal? Have I been taking Wellbutrin for too short a time to really see if it works or not? Are these side effects? Should I get off this medication? =/ Thanks so much, this is really stressing me out...

I'm thinking of the mechanisms used to test g-forces on pilots, but instead, in a frisbee-like structure (like a space station), which is then surounded by another similar structure spinning alternately and accounting for the differences between the two structures to compensate for speed. Could there be practical uses for propulsion?

At my work, making coffees, several employees use steam to compress milk containers for the trash. Heres what they exactly do: They take the steam wand, insert it into the gallon jug hole, push in steam until the it reaches 150degrees. The result is a very hot milk container. Then they compress it. The gas that is pushed out is rather unpleasant smelling. Obviously there is some reaction between the heat or water vapor and the plastic jug.

Is this a health hazard? I looked up benzene then styrene and noticed styrene is a suspected carcinogen.
