Why do you think the chemicals have to be heated in the flame first before the colored light is emitted? A) the heat excites electrons and light is emitted upon relaxation B) the heat ionizes the salts C) the heat removes solvent (water) so that the light from the salts is visible D) the combustion products in the flame undergo electron transfer reactions with the salts
