Yeah, someone else did the IR/NMR for me.
The smallest peak is CDCl3 and it seems that setting it to 0 is prudent.
I did some thorough review of NMR/IR and I'm pretty confident now!
Thanks guys!
In examining the IR spectrum, I noted that there were peaks for CH2-x where x is bromine, methylene (2 peaks) and a peak corresponding to a methyl group; I concluded that I've synthesized n-bromobutane. Is the method I used to interpret my spectra sound? *CDCl3 was the IR solvent
In addition...
Homework Statement
∫ \frac{5e^{\frac{1}{y}}}{3y^{2}}
Homework Equations
u=5e^{\frac{1}{y}}
u'= -5e^{\frac{1}{y}}
The Attempt at a Solution
I keep getting: -\frac{5e^{\frac{1}{y}}}{3y^{2}} +c but I know that there shouldn't be a y^{2} in the denominator.
Hey guys!
I've been a biochem major for a little while but I recently took a calculus course and received an 89 and I found that although mathematics may seem a little tedious, I truly love it. In addition, I really like chemistry but mainly the the manners in which physics impacts chemistry...
Homework Statement
x^3-8x+10=0
Homework Equations
The Attempt at a Solution
By dividing by x-1 (1 is a factor of the solution), I got (x-1)(x2+x-7)+3+10=0
which equals x^3-8x+20=0
I think the solution would be imaginary but I used a graphing calculator and there is one...
20°C is is greater than -95°C (melting ) so acetone would not have melted and is less than 56°C (boiling) so acetone would not have evaporated; I'm assuming the normal phase of acetone is liquid and you don't merely assume because something hasn't melted or boiled that it is solid? Is my...
I was reviewing a chart of Physical properties of pure substances (20 °C)
Acetone has a melting point of -95°C and boiling point of 56°C so you'd assume it's solid (but obvioulsy it's liquid). In addition, Diphenyl has a melting point of 70°C and boiling point of 255°C so you'd assume it's...

I've not written a lab report since prep school and I need some critiques (thorough).

The Attempt at a Solution
I'm an undergraduate and my school has quite a small chemistry department and lacks the resources of many other schools (i.e. we have less than "ideal" equipment). Are you saying that a hot plate would supply a more even and efficient heat (i.e. less heat dissipating into the environment)?
At...
I was heating water in lab and it took approximately 25 minutes to raise the temperature of my water by 65 degrees Celsius; perhaps the flame wasn't sufficient? I made certain that I could the the reducing and oxidizing flame, yet the liquid heated quite slowly. In addition, the flame was...
