2 Calculate the total number of microstates and the entropy of a system with a volume of 10 m3, which is notionally divided up into 10,000 equal sized compartments and which contains one mole of an ideal monatomic gas. Now calculate the number of microstates and the entropy of the same system if the gas has expanded to fill 20 m3. Calculate the change of entropy for this system assuming the expansion was isothermal.

If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

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.

What will most likely happen when two bromine atoms bond together?
