Homework Statement
A converging lens has a focal length f, and a diverging
lens has a focal length –f, which has the same magnitude
as the converging lens. They are separated by a distance
D which is greater than f, as shown. Parallel light enters
from the left. Will the light be brought...
Homework Statement
If, in the separation of ether solution from aqueous NaOH layer, som eof the aqueous layer was left behind in the conical tube with the ether solution, how would the experimental value of benzophenone (the compound in the ether solution that is being isolatey) recovery be...
Homework Statement
A uniform, spherical bowling ball of mass m and radius R is projected horizontally along the
floor at an initial velocity v0 = 6.00 m/s. The ball is not rotating initially, so w0 = 0. It
picks up rotation due to (kinetic) friction as it initially slips along the floor...
ah each of the questions are separate. for the first question concerning methanol, that one doesn't really have a question. It just says "Discuss and conclude", so I just wanted to check my data and stuff. The second question is an extension of the first, still with methanol, and the question...
Homework Statement
So I did a simple distillation lab and discovered that my unknown was methanol (boiling point was around 65). But, I just wanted to check something: since the alcohol was impure, shouldn't the boiling point range of the unknown be above pure methanol's boiling point and...
