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.)

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
