Final answer:
The reaction between 1 mol of NO₂ and 4 mol of H₂O does not match standard stoichiometry of typical reactions with NO₂ and water. The correct balanced equation for NO₂ reacting with water is 2 NO₂ + H₂O → HNO₃ + HNO₂. For the given reference, 0.669 mol of NH3 would produce 1.0035 mol of H₂O when reacted with oxygen.
Step-by-step explanation:
The student has asked for the balanced chemical equation when 1 mol of NO₂ reacts with 4 mol of H₂O. However, the reaction between NO₂ and H₂O is not a straightforward reaction; typically, NO₂ reacts with water in the atmosphere to form nitric acid (HNO₃) and nitrous acid (HNO₂), which is a disproportionation reaction. The balanced equation for this reaction is: 2 NO₂ + H₂O → HNO₃ + HNO₂. If we were to take the provided ratio of NO₂ to H₂O, it does not match the typical stoichiometry of NO₂ reactions with water.
For the examples provided in the reference information, if 0.669 mol of NH3 react according to the balanced chemical equation 4NH3(g) + 5O2(g) → 4NO(g) + 6H₂O(l), the amount of H₂O produced can be calculated using the stoichiometric coefficients. Since for every 4 mol of NH3 that react, 6 mol of H₂O are produced, it follows a 4:6 or a 2:3 ratio. Therefore, 0.669 mol of NH3 would produce (0.669 mol NH3) * (3 mol H₂O / 2 mol NH3) = 1.0035 mol of H₂O.
The correct answer involves a stoichiometric calculation based on the coefficients provided in the balanced chemical equation, which represents the molar ratio in which substances react.
