Acid rain can damage the galvanized coating on metals meant to protect them from outdoor weather according to the reaction: Zn(s) + H2SO4(aq) → H2(g) + ZnSO4(aq). If you collect 0.25 L hydrogen gas when this reaction is performed in the lab but 0.31 L were predicted by calculation, what is the percent yield?

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.
