Balancing the Chemical Equation NH3 + O2 -> NO + H2O

To balance the chemical equation NH3 + O2 -> NO + H2O using the method of electrical balance, 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 counting the number of atoms for each element in the unbalanced equation:

On the left side: - Nitrogen (N): 1 atom - Hydrogen (H): 3 atoms - Oxygen (O): 2 atoms

On the right side: - Nitrogen (N): 1 atom - Hydrogen (H): 2 atoms - Oxygen (O): 1 atom

To balance the equation, we need to adjust the coefficients in front of each compound. Here's the step-by-step process:

1. Balance the elements that appear in the fewest compounds first. In this case, it's Nitrogen (N). Since there is already 1 atom of Nitrogen on both sides, it is already balanced.

2. Next, balance the Hydrogen (H) atoms. There are 3 Hydrogen atoms on the left side and 2 Hydrogen atoms on the right side. To balance them, we can place a coefficient of 2 in front of H2O on the right side, giving us:

NH3 + O2 -> NO + 2 H2O

Now, the Hydrogen atoms are balanced with 6 atoms on both sides.

3. Finally, balance the Oxygen (O) atoms. There are 2 Oxygen atoms on the left side and 4 Oxygen atoms on the right side. To balance them, we can place a coefficient of 2 in front of NO on the right side, giving us:

NH3 + O2 -> 2 NO + 2 H2O

Now, the Oxygen atoms are balanced with 4 atoms on both sides.

The balanced equation is:

NH3 + O2 -> 2 NO + 2 H2O

Please note that this is a balanced equation using the method of electrical balance. However, it's always a good practice to double-check the balanced equation to ensure accuracy.
