The reaction of XeF₆ with a limited amount of quartz gives compound A. Then on reaction with an equivalent amount of XeO₃, A gives B. The products A and B are, respectively

Concept:

• Xenon is a chemical element with the symbol Xe with atomic number 54. Xenon (Xe) is a dense, colorless, odorless noble gas available in the atmosphere of the earth in a trace amount. 
• Quartz is a hard, crystalline mineral composed of silica. It has a molecular formula of \(Si{O_2}\).

Explanation:

• The reaction of \(Xe{F_6}\) and \(Si{O_2}\) forms \(XeO{F_4}\), by the following reaction 

​\(2Xe{F_6} + Si{O_2} \to 2XeO{F_4} \;+SiF_4\)  . So, the product A is XeOF4.

• Now, the reaction of XeOF₆ with XeO₃ forms XeO2F2 by the following reaction, 

​\(XeO{F_4} + Xe{O_3} \to 2Xe{O_2}{F_2}\). So, the product B is XeO2F2.

• Thus, the reaction of XeF6 with a limited amount of quartz gives compound A. Then on reaction with an equivalent amount of XeO3, A gives B. The products A and B are, respectively XeOF4 and XeO2F2.

Conclusion: 

• Hence, the products A and B are, respectively XeOF4 and XeO2F2.
