A stream of air (21 mole% O2, 79 mole% N2) flowing at a rate of 15.0 kg/h is mixed with a stream of CO2 of unknown temperature. The pressure of the CO2 stream is 1 atm and enters the mixer at a rate of 20.0 m 3 /h. If the mole percent of CO2 in the product stream is 52.55%, what is the temperature of the stream of CO2 which enters the mixer

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.
