Answer 2

Balancing the Chemical Equation Fe + HNO3 = Fe(NO3)2 + NO + H2O

To balance the chemical equation Fe + HNO3 = Fe(NO3)2 + NO + H2O using the method of electronic balancing, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's start by balancing the atoms of each element one by one:

1. Balancing Iron (Fe): - There is one Fe atom on the left side and one Fe atom on the right side. Fe is already balanced.

2. Balancing Nitrogen (N): - There is one N atom in HNO3 on the left side and two N atoms in Fe(NO3)2 and NO on the right side. We need to balance the N atoms. - To balance the N atoms, we can place a coefficient of 2 in front of HNO3 on the left side: 2 HNO3. - The equation now becomes: Fe + 2 HNO3 = Fe(NO3)2 + NO + H2O.

3. Balancing Oxygen (O): - There are three O atoms in HNO3 on the left side and six O atoms in Fe(NO3)2 and H2O on the right side. We need to balance the O atoms. - To balance the O atoms, we can place a coefficient of 3 in front of HNO3 on the left side: 2 HNO3. - The equation now becomes: Fe + 2 HNO3 = Fe(NO3)2 + NO + 3 H2O.

4. Balancing Hydrogen (H): - There are six H atoms in 2 HNO3 on the left side#### Balancing the Chemical Equation Fe + HNO3 = Fe(NO3)2 + NO + H2O

To balance the chemical equation Fe + HNO3 = Fe(NO3)2 + NO + H2O using the method of electronic balance, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The balanced chemical equation for the reaction is as follows: Fe + 8HNO3 = Fe(NO3)3 + 2NO + 4H2O

This balanced equation ensures that the number of each type of atom is the same on both sides of the equation.

The balanced coefficients are as follows: - Fe: 1 - HNO3: 8 - Fe(NO3)2: 0 - NO: 2 - H2O: 4

This balanced equation satisfies the law of conservation of mass and charge.
