If you are given a structural drawing, or 3-D model, of a compound and told that it is an acid, what features of the structure could you use to determine if the acid is strong or weak?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
