This is a 3 part problem, and I pulled the wavelengths directly from the printed text on the page. Just double checked and their right.
Well, if the energy ratio is ~1.6:1, that means the blue arrow should be ~0.6*yellow arrow. So that small gap is supposed to represent the 0.6, which means we...
Sorry, let's say the wavelengths of the yellow and blue lights, respectively, are:
610 nm and 390 nm
How would I determine where the arrows are drawn using the ratio of these numbers?
Yes, I know blue light has more energy than yellow light. Does that mean that for blue light, the arrow would be drawn from 3 to 1, and for yellow light from 2 to 1?
Show, using directional arrows, which transition corresponds to...
An energy level diagram is provided. Show, using directional arrows, which transition corresponds to the yellow light and which transition corresponds to the blue light.

A pair of students found the temperature of 100 g of water to be 27.0°C. They then dissolved 6.32 g of KOH in the water. When the salt had dissolved, the temperature of the water was 42.5°C.
If the temperature of the water is raised, doesn't that mean it retained heat, thus showing that the...
Calculate the pH of a 0.0253 M aq solution of a monoprotic acid. The Ka for the acid is 1.79 x 10-2
So a monoprotic acid will have the form HA --> H + A, correct?
I 0.0253 0 0
C -x x x
E (0.0253-x) x x
EDIT: I just realized the...
The book shows that the concentration of OH is 2(.1475M), but I'm not sure how that was obtained. I understand that there are 2 hydroxide ions, but why do we use the moles of the solution?
A solution is prepared to be 0.1475 M in Sr(OH)2. Find the [H3O+], [OH‐], pH, and pOH.
I'm not quite sure where to go from here. I was thinking I can start by writing out the net ionic equation:
Sr(OH)2 → Sr2+ + 2OH-
But I don't really know how that helps me. Any insights?
