Text Solution

Verified by Experts

The correct Answer is:
1
`Fe` forms ammonium nitriate with very dilute nitric acid:
`4Fe+10HNO_(3)rarr4Fe(NO_(3))_(2)+NH_(4)NO_(3)+3H_(2)O`
it forms nitrous oxide with dilute nitric acid:
`4Fe+10HNO_(3) rarr4Fe (NO_(3))_(2)+N_(2)O+5H_(2)O`
With concentrated nitric acid it forms nitrogen dioxide
`Fe+6HNO_(3)rarrFe(NO_(3))_(3)+3NO_(2)+3H_(2)O`
