The volume of gas in the bell jar is 1000cm3 , calculate the volume of gas you would expect to remain in the bell jar at the end of the experiment assume that all the oxygen is used up 2Mg + O2 = 2MgO

How does a sample of helium at 15 degree celsius compare to a sample of helium at 215 k? a) the helium at 15 degrees celsius has a higher average kinetic energy that the sample at 215 k. b) the helium at 15 degrees celsius has lower nuclear energy that the sample at 215 k. c) the helium at 15 degrees celsius has slower- moving atoms that the sample at 215 k. d) the helium at 15 degrees celsius has smaller atoms than the sample at 215 k.
