Answer:
During the reaction zinc combines with NO3, and the hydrogen combines with oxygen to form water, and there is a release of NO2 gas. Zinc reacts with Nitric acid to generate hydrogen and make a solution of zinc nitrate: Zn * 2 HNO3 - Zn(NO3)2 * H2.

Explanation:
With cold, dilute nitric acid, zinc liberates nitric oxide (NO), along with soluble zinc nitrate and water.
3 Zn + 8 HNO3 = 3 Zn(NO3)2 + 2 NO + 4 H2O
But with hot, concentrated HNO3, reddish brown nitrogen dioxide (NO2) is produced.
Zn + 4 HNO3 = Zn(NO3)2 + 2 NO2 + 2 H2O
