For "moving toward," a blue ray of light moved from the star to Earth. Then a spectrum appeared in the bottom half of the screen. Which statement about the spectrum on the bottom relative to the spectrum of the stationary star is correct?

It travels faster

Explanation:

The spectrum are likely to be of different  wavelengths. The different wavelengths result in light of a different intensity. This results in a light difference in the spectrum. The blue ray generally presents light of shorter wavelengths. It is associated with close to hottest objects. Thus, there will bee a difference in the two spectra.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
