Question

Gaseous iodine pentafluoride, IF,, can be prepared by the reaction of solid iodine and gaseous fluorine: L(s)+5F, (g)+21IF, (g) A 4.80 -L flask containing 9.60 g I2 is charged with 9.60 g F2, and the reaction proceeds until one of the reagents is completely consumed. After the reaction is complete, the temperature in the flask is 125 °C
