- The mole ratio of NH3 to N2 in the balanced chemical equation 4NH3 + 3O2 → 2N2 + 6H2O is found by comparing the coefficients of NH3 and N2. For every 4 moles of NH3 that react, 2 moles of N2 are produced. Therefore, the mole ratio of NH3 to N2 is 4:2.
- However, this ratio can be simplified by dividing both sides by 2, which gives us a simplified ratio of 2:1. So the correct answer, in terms of the simplest whole number ratio, is not explicitly listed among your choices. The closest answer provided to the simplified ratio is B) 4:2, which should simply be reduced to B) 2:1.
