In a lab experiment monitoring the change in concentration of a reddish-brown substance, FeNCS2+, a wavelength of 455 nm is used.

a. Does this wavelength agree with your conclusions about beam color, solution color, and absorbance above? Why or why not?

b. What other wavelengths might you consider using for FeNCS2+ spectroscopy?

Calculate the frequency of a wave in a spring toy. the wave has a speed of 1.1 meters per second and a wavelength of 0.1 meters. *

4. propanol and isopropanol are isomers. this means that they have a) the same molecular formula but different chemical properties. b) different molecular formulas but the same chemical properties. c) the same molecular formula and the same chemical properties. d) the same molecular formula but represent different states of the compound

Which is the most concentratic acid
