Question

_HNO3+ Fe+2

Answer 1

Answer: The coefficient for water after the equation is balanced is 2.

Explanation:

The balanced chemical equation must have same charge and same number of atoms on both sides of the equation.

As the given reaction is a redox recation occuring in acidic medium.

$HNO_3+3Fe^{2+}+3H^+\rightarrow NO+3Fe^{3+}+2H_2O$

The coefficient for water will be 2 after the equation is balanced.
