Chemistry - July 2006

Water is not the answer. I need a substance that will boil at around 90 degrees F. and with a higher expansion rate, and that will not explode or ignite with heat or open flame.

If you just stare at a computer or TV screen, you see what you are supposed to see. However, if you look at either through a camera, you see dark stripes continously on the screen. What causes this?

I have a coordless phone that came with NiCad batteries but it is having problems with those batteries. The only rechargable batteries I have on hand are NiMH. Is it ok to use NiMH batteries in a phone that was probably specifically designed to run off and charge from NiCad batteries.

Strange note: the phone seems to think the NiCad batteries are alkaline and refuses to charge them, but seems to have no issues with charging to NiMH batteries.

I was wondering if someone could perhaps EXPLAIN how to solve this problem. =]
Assume that element Uus is synthesized and that it has the following isotopes:
284Uus (283.4 amu) 34.60%
285Uus (284.7 amu) 21.20%
288 Uus (287.8 amu) 44.20%
What is the value of the average atomic mass for Uus that would be listed on the periodic table? [please use significant figures]

I don't even know how to begin this problem. x] Thanks to anyone that can help. :]

Beside water and bleach, what else should go into the mix to make a good counter-top cleaner and disinfectant?

I like Clorox product called "CLEAN-UP" but I don't like paying close to $4 a bottle . I've tried making my own solution but the spray bottle's syphon tube winds up getting clogged with some sort of black percipitate.

So what should I add to buffer the reaction inside the solution? (regular liquid dishsoap doesn't help the problem either)
