The color of light from which the surface of potassium can eject with a higher kinetic energy is to be determined. Concept introduction: The photoelectric effect refers to the ability of a light beam to eject photoelectrons from a surface of a metal when the light is directed on to the surface of the metal. There, we can calculate the maximum kinetic energy of the ejected electrons using the following equation. E max = 1 2 m v e 2 = h v − ϕ

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. . If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T X O O лет-ле HO OH HO OH This transformation can't be done in one step.
