$1 mole Zn + xHNO_{3} (70%) ⟶ Zn (NO_{3})_{2} +$ $____$ $+$ $____$

In above reaction value of x is

Answer:

Solution:

The reaction of zinc with 70% nitric acid (a concentrated acid) produces zinc nitrate, nitrogen dioxide, and water.

The balanced chemical equation is:

$Zn + 4 HNO_{3} (70%) ⟶ Zn (NO_{3})_{2} + 2 NO_{2} + 2 H_{2} O$

Comparing this to the given equation, the value of x is 4.
