Answer to Question #172462 in General Chemistry for Jin

Question

Problem : Iodine pentafluoride is an incendiary agent , which is a substance that ignites combustible materials . Iodine pentafluoride is usually made by passing fluorine gas over solid iodine , but it also forms when iodine monofluoride changes into the element iodine and iodine pentafluoride . Shown in the reaction : How many moles of element iodine form when 15 moles of iodine monoflouride react completely ?

Answer 1

Chemical reaction occur is

5IF=2I₂ + IF₅

5IF = 2I₂

I₂ Produced = (2/5)×15 moles

I₂ Produced = 6 moles

6 moles of elemental iodine (I₂) is produced when 15 moles of iodine monofluoride (IF) react completely
