Fe2O3 + 2A1 - Al2O3 + 2Fe
How many moles of iron (Fe) would be produced if
2.50 mol Fe,03 react? Make sure to use the
correct number of significant figures in your
answer.
2.50 mol Fe2O3 =
mol Fe

What is the atomic number of an atom that has 6 protons

How many atoms are in 2 moles of phosphorus?

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.
