Xenon hexafluoride was one of the first noble gas compounds synthesized. the solid reacts rapidly with the silicon dioxide in glass or quartz containers to form liquid xeof4 and gaseous silicon tetrafluoride. what is the pressure in a 1.00−l container at 25° c after 8.53 g of xenon hexafluoride reacts? (assume that silicon tetrafluoride is the only gas present and that it occupies the entire volume.)

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.

1. jay fills a wagon with sand (about 20 kg) and pulls it with a rope 30 m along the beach. he holds the rope 25° above the horizontal. the rope exerts a 20-n tension force on the wagon. how much work does the rope do on the wagon?

What organization and environment is described above?
