Well the reactions we've been doing have concerned creating amides, reducing them, and reactions with carboxylic acids. Mostly substitution/elimination stuff, I suppose. This also falls in line with Gabriel synthesis, Mannich reactions, etc. Is there not just a general rule here?

This is a general Organic Chemistry question. How do the reactivities of the following compare? Acyl Chlorides, Esters, Anhydrides, Amides, Ketones, Aldehydes The Attempt at a Solution I know the following "ladder:" MOST REACTIVE acyl chloride anhydride ester amide LEAST...

Yeah, that's what I did..I said that the V at 20 ms was 15 (the peak). Should I just pick another arbitrary time?

Homework Statement You see this trace on your oscilloscope for an RC circuit. The vertical scale is 5volt/square and the horizontal scale is 50ms/square. What is the time constant of the RC circuit? Homework Equations Vc(t) = Vo(e^(-t/RC) Vr(t) = -Vo * e^(-t/RC) t halftime = Tln(2) =...

Awesome. Thanks for the help!

So if the magnetic force on the wire is upward, then the magnet itself will push downward, resulting in a weight gain. Right? Thanks for the links, also. Much more informative than my prof's lecture notes.

[SOLVED] Magnetic force on a charge carrying wire Homework Statement A current carrying wire is in a magnetic field as shown below. The magnet is on a scale. Given this setup, does the scale read more or less weight? Explain using the Right Hand Rule and Newton's Third Law. Note: The...

When you added for 17/72 and 10 in parallel, shouldn't it have been 1/4.235+1/10 = 1/R = 2.975? so then with ------3-------- | | 20 2.975 | | ------------ So now which should I combine first?

So then 20 and 3 are in series, right? 20+3=23 ohms So now my drawing has: 23 ohms . 4 ohms 4.235 ohms . 6 ohms Would the 4 and 6 be considered series?

Thanks guys; apparently I didn't quite understand how to combine initially. I get it now!

Homework Statement Find the equivalent resistance between points A and B in the drawing. Homework Equations Rseries = R1+R2+R3... Rparallel: 1/Rp = 1/R1+1/R2+1/R3... The Attempt at a Solution Reducing it down: 1/8+1/9 = 1/R1 = 4.235 That's in parallel with 20, so...

[SOLVED] Capacitance in series and parallel circuit Homework Statement Determine the equivalent capacitance between A and B for the group of capacitors in the drawing. Homework Equations Cseries = 1/Cs = 1/c1 + 1/c2 + ... Cparallel = Cp = C1 + C2 + ... The Attempt at a Solution...

Ok so any other ideas?

Homework Statement The human lungs can function satisfactorily up to a limit where the pressure difference between the outside and inside of the lungs is 1/20 of an atmosphere. If a diver uses a snorkel for breathing, how far below the water can she swim? Assume the diver is in salt water...

So I totally overanalyzed that one... oh well. Thanks for the help!
