Why not? Ethyl acetate and methyl isobutyl ketone are pretty nonpolar solvents. Several rubbers and plastics impervious to ethanol are easily damaged by both of these solvents. The OP said "regularly washed in a bath of ethanol", so I assumed exposure time = indefinite ("bathed" in the ethanol)...

And so can ethyl acetate and methyl isobutyl ketone -- from the OP! Hence why I said Secondly, Everything depends on the concentrations of denaturants involved, not just their compositions. (Unfortunately, Walgreens does not specify concentrations...) Thirdly, If the OP can well handle...

If it's just naphtha that concerns you, how about just http://www.walgreens.com/store/catalog/Antiseptics/Apothecary-Ethyl-Rubbing-Alcohol-70/ID=prod475-product?

Have you tried creating a Ramdisk?

Hey guys, I'm a senior at UC Santa Cruz, double major in Computer Science (B.S) and MCD Biology (B.S.) (i.e., Micro-, Cell, and Developmental Biology). Pretty much, I'm trying to get a job after college when I graduate in June, (can involve anything covered by either field). Ideally, I...

yes, that is correct

Not quite -- 1) Oxygen is a diatomic gas (O2) 2) Check your units -- your gas constant (and consequently the volume) is off by (about) two orders of magnitude! _For your units, the gas constant is approximately 0.0821 L*atm/(K*mol)

Hint: Ideal Gas Law (PV = nRT)

I am pursuing three majors at UC Santa Cruz, but they are all quite related* (pure math, computer science, biochemistry-molecular biology**), which can be completed altogether in four years (12 quarters), taking ~5 courses per quarter (recommended general courseload ~3 courses / quarter at...

Are you familiar with tautomerization?

Depending on the pressure, solid CO2 can exists in several interesting phases See https://www.llnl.gov/str/Yoo.html and their paper http://www.sciencemag.org/cgi/content/abstract/283/5407/1510?ck=nck

Quite a fortunate opportunity >> Take whatever money you wish, seek to tutor him better than others...

Most likely :)

I doubt it, though it is possible for some statistically minute quantity of 3-nitrophthalic acid to react exactly as such

Roughly put, 1) Lone pair on hydrazine attacks carboxylic carbon 2) Proton transfers from hydrazine to carboxylic -OH 3) Condensation: one water molecule (i.e., protonated hydroxyl) removed (& formation of amide bond) 4) Repeat steps 1-3 for the other carboxylic acid group, with the remaining...
