Question

Which of the following is incorrect for nitrogen pentoxide?
A. In the gas phase, `N_(2)O_(5)` decomposes with explosion into `NO, NO_(2)` and `O_(2)`
B. It reacts with concentrated `H_(2)SO_(4)` to produce `NO_(2)^(+)`
C. It is relatively inert
D. It acts as a strong oxidising agent

Answer 1

Correct Answer - 3
it is highly reactive. It affects organic substances such as cork, rubber ect. It oxidises iodine readily into iodine pentoxide:
`I_(2)+5N_(2)O_(5)rarrI_(2)O_(5)+10NO_(2)`
`N_(2)O_(5)+3H_(2)SO_(4)rarrH_(3)O^(+)+2NO_(2)^(+)+3HSO_(4)^(-)`
