Chlorine trifluoride, ClF₃, is a valuable reagent because it can be used to convert metal oxides to metal fluorides:

(a) What mass of NiO will react with ClF₃ gas if the gas has a pressure of 250 mm Hg at 20°C in a 2.5-L flask?
(b) If the ClF₃ described in part (a) is completely consumed, what are the partial pressures of Cl₂ and of O₂ in the 2.5-L flask at 20°C (in mm Hg)? What is the total pressure in theflask?
