Solution

Dear Student.

$Dilute nitric acid reacts with zinc to give zinc nitrate and nitrous oxide 4 Zn + 10 {HNO}_{3} \to 2 N_{2} O + 4 Zn ({NO}_{3})_{2} + 5 H_{2} O Concentrated nitric acid reacts with zinc to give zinc nitrate and nitrogen dioxide 4 Zn + 4 {HNO}_{3} \to 2 {NO}_{2} + Zn ({NO}_{3})_{2} + 2 H_{2} O$
