When sodium is heated, a yellow spectral line whose energy is 3.37 x 10-19 J per photon is produced. Plank’s constant, h, equal 6.626 x 10-34 J•s. a) What is the frequency of this light. b) What is the
wavelength of this light? Show all equations, work, and units.

3.) for each of the following compounds, draw the major organic product of reaction with hcl or naoh and circle whether the starting materials and products will be more soluble in organic solvent or water benzoic acid + hcl: benzoic acid + naoh: oh benzoic acid water/organic water organic fluorenone hс: fluorenone + naoh: fluorenone water/organic water/organic веnzocaine + hci: benzocaine + n»oh: h2n benzocaine water/organic water organic o=

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

Mike and mitchell decide to have a foot race. they mark off a stretch of 100 yards, and recruit cindy to work the stopwatch. after running the race and looking at the results, cindy declared that mitchell was the fastest. so how did the boys times compare?
