Test 2
For test 2 and future tests/exams, are we suppose to memorize constants, conversions, or any formulas? Also for wavelength, which units are preferable, m or nm?

Re: Test 2 [ENDORSED]
On the Chem 14A website, there is a link titled constants and equations.. this is what will be given to us, everything else other than a periodic table is what we would have to know. As far as wavelength I think either is okay as long as the question does not specify but remember in terms of the equations you would use the unit m.

Re: Test 2
If you recall from test 1, we were given a cover sheet of constants and equations. I know that same cover sheet is being provided for test 2 and test 3, but I am not positive about the midterm/final. As for the units, as long as the question does not specify, you are free to use whichever. nm are usually more practical.

Re: Test 2
for the test we are going to be given the constant but I do believe that we might need to know the formulas that we are to use.

Re: Test 2
In short, no we are not expected to memorize the formulas since we will be provided a formula and constant sheet for all exams. However, we will be expected to know which formula to use and how to appropriately manipulate the formula for the given question. (i.e. p*c = ((h*c)/λ) ----> p = (h/λ) or E = h*v = h(c/λ)). And the preferred units for wavelength will be dependent on what units are asked for in the question.
