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?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
