if 12 atoms of iron are reacted with 6 molecules of oxygen gas, which is the limiting reactant and how many reactant and how many atoms or molecules will be left over

How does climate change cause the ocean's thermohaline current to slow down?

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

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.
