Two identical flasks of equal volume are kept at the same temperature. Flask A contains argon (Ar) and flask B contains krypton (Kr). If the pressure inside both flasks is measured to be the same and we assume the gases behave as ideal gases, which answer correctly completes the following statements: (i) The average kinetic energy of the atoms in flask A is the average kinetic energy of the atoms in flask B. (ii) On average, the atoms in flask A are moving than the atoms in flask B.

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
