Answer:
To determine the total number of nitrogen atoms on the right-hand side of the chemical equation, we need to examine the nitrogen-containing compounds:
HNO3(aq) and NO2(g)
In HNO3(aq), there is 1 nitrogen atom. Since we have 4 moles of HNO3 in the equation, we multiply the nitrogen atom count by 4.
In NO2(g), there are 2 nitrogen atoms. Again, we have 2 moles of NO2, so we multiply the nitrogen atom count by 2.
Total number of nitrogen atoms on the right-hand side:
4 moles of HNO3 * 1 nitrogen atom/mole of HNO3 = 4 nitrogen atoms
2 moles of NO2 * 2 nitrogen atoms/mole of NO2 = 4 nitrogen atoms
Adding these two values together, we get:
4 nitrogen atoms + 4 nitrogen atoms = 8 nitrogen atoms
Therefore, there are a total of 8 nitrogen atoms on the right-hand side of the chemical equation.
