It would be nice to know if this was an inorganic or organic compound – but I'll just assume it's organic.
1) Make sure all your glassware is clean
2) Be careful handling the solid – you are only given on sample – divide it into two and place 1/2 in a separate labeled vial for your final tests. Use only a SMALL amount for each test you do, and don't leave it laying around uncovered or stoppered.
3) Check solubility first (these are all test tube tests)
a) acid (could be an amine, or a aniline, or a amide)
b) base (could be a carboxylic acid or a phenol)
c) water (polar)
d) toluene (nonpolar – possible aromatic ring)
4) Take melting point (is it sharp? ==> if no ==>
find a recrystallization solvent – a solvent that it will dissolve when hot, but solidify when cooled, this may take hours!
Yes, CO2 can weaken a standardized base. The result will be that an unknown acid will appear to have a slightly HIGHER molarity than actual. Often, standardized bases are protected from atmospheric absorption of CO2 by passing air that enters the base container through a KOH absorber that traps the CO2 before it can weaken the base.
Near the beginning of his book, Nicolas Taleb uses the example of a gratuitously fed turkey. The turkey experiences a black swan event at the day it’s slaughtered. So I think it’s irrelevant wether or not an event is or can be predicted by other people. The question is just if the individual/actor exposed to the risk of the black swan realizes this fact. The turkey did not, nor did many bankers.
It is not possible for you or your service provider. If it is unknown to you it is also unknown to your service provider and neither you nor they can block something that is not there
Well, it depends on the escape speed of that particular black hole, but if it's black and it's a hole, you must be faster than the light, so it doesn't matter if you have to run c+1 mps or c+c+c+c+c, you still can't escape it. And that's first of all because nothing can travel at such a speed and nothing can survive on the surface of the black hole (not even quantum particles) so there's nothing to escape.
Trendy Summer Nails
At the end of this summer, when the heat is gradually fading off, it's time to try new colors on your nails to match with clothes. These gorgeous fake nails are also great choice. Enjoy your trendy summer nails!

try ethyl acetate
ethyl acetate mixed with various % hexane (5,10, 15, 20 ,etc)
alcohol
methanol
toluene
isopropanol
alcohol/%H2O (like hexanes above)
6) Get good MP
7) Take Infrared spectrum to get functional groups
with a MP, IR, and functional groups you should be able to get a pretty good idea of what you compound is!!
NOW
yup! Don't look like I'm trying to "phone home" anymore! Now it's bright green & giant from the gauze.
my fav color!

usually it's 4, but if you fill the pans really full, then plan on 3

If you have a graph of absorbance vs concentration, then the equation describing the line will be
Abs = (slope) * conc
(in the form y = mx + b, where the intercept b should be zero, since zero material will not absorb)
Then, the equation is
Abs = 0.066 L/mg * conc
Plug in the value for absorbance and solve for concentration.
conc = Abs / 0.066 L/mg
= 0.11 / 0.066 L/mg
= 1.67 mg/L
