Answer 3

Balancing the Equation using the Electron Balance Method

To balance the equation HNO2 + HJ = J2 + NO + H2O using the electron balance method, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's break down the equation and balance it step by step:

1. Start by counting the number of atoms of each element on both sides of the equation: - H: 3 hydrogen atoms on the left side (2 from HNO2 and 1 from HJ), and 3 hydrogen atoms on the right side (2 from H2O and 1 from HJ2). The hydrogen atoms are already balanced. - N: 1 nitrogen atom on the left side (from HNO2), and 1 nitrogen atom on the right side (from NO). The nitrogen atoms are already balanced. - O: 3 oxygen atoms on the left side (2 from HNO2 and 1 from H2O), and 3 oxygen atoms on the right side (2 from NO and 1 from J2). The oxygen atoms are already balanced. - J: 1 iodine atom on the left side (from HJ), and 2 iodine atoms on the right side (from J2). The iodine atoms are not balanced.

2. To balance the iodine atoms, we need to add a coefficient in front of HJ on the left side and J2 on the right side. Let's assume the coefficient for HJ is a and the coefficient for J2 is b.

The balanced equation becomes: aHJ + HNO2 = bJ2 + NO + H2O

3. Now, let's balance the iodine atoms: - J: a iodine atoms on the left side (from aHJ), and 2b iodine atoms on the right side (from bJ2). To balance the iodine atoms, we need to set a = 2b.

The balanced equation becomes: 2bHJ + HNO2 = bJ2 + NO + H2O

4. Finally, let's balance the hydrogen, nitrogen, and oxygen atoms: - H: 2a hydrogen atoms on the left side (from 2bHJ), and 2 hydrogen atoms on the right side (from H2O). To balance the hydrogen atoms, we need to set a = 1. - N: 1 nitrogen atom on the left side (from HNO2), and 1 nitrogen atom on the right side (from NO). The nitrogen atoms are already balanced. - O: 2 oxygen atoms on the left side (from HNO2), and 2 oxygen atoms on the right side (from NO and H2O). The oxygen atoms are already balanced.

The final balanced equation is: 2HJ + HNO2 = J2 + NO + H2O

Therefore, the coefficients for the balanced equation are: - Coefficient for HJ: 2 - Coefficient for HNO2: 1 - Coefficient for J2: 1 - Coefficient for NO: 1 - Coefficient for H2O: 1

The balanced equation is: 2HJ + HNO2 = J2 + NO + H2O.
