Which of the following can be determined using only the coefficients of the balanced chemical equation for the reaction N₂(g) + 3H₂(g) → 2NH₃(g)?

Question

Quizplus · Accepted Answer

The coefficients in a balanced chemical equation represent the mole ratios between the reactants and products. Therefore, the number of moles of one substance can be determined if the number of moles of another substance is known. In this case, if 4.2 mol of N₂ react completely, we can use the coefficient in front of N₂ (1) to determine that 1 mol of N₂ produces 2 mol of NH₃. Therefore, 4.2 mol of N₂ will produce 2 x 4.2 mol = 8.4 mol of NH₃.
