Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.

How does a nuclear reactor produce electricity? a. high-energy gamma rays are converted by a generator into electricity. b. the heat from the reaction turns water to steam, which runs a generator. c. the reaction produces a stream of electrons that flow through wires and into batteries. d. the heat released from the reaction is used to burn coal or gas to produce electricity. e. control rods absorb the neutrons emitted and release a stream of electrons as electricity.
