To balance the chemical equation NH₃ + O₂ → NO + H₂O, the correct balanced equation is 4 NH₃ + 5 O₂ → 4 NO + 6 H₂O. This aligns the number of nitrogen and oxygen atoms on both sides of the equation.
The student appears to be asking how to balance the chemical equation of nitrogen and hydrogen reacting with oxygen to form nitrogen monoxide (NO) and water (H₂O). To balance the chemical equation NH₃ + O₂ → NO + H₂O without fractions, the balanced equation is 4 NH₃ + 5 O₂ → 4 NO + 6 H₂O. This ensures that the numbers of N and O atoms on either side of the equation are now equal.
For another example from the given information, the synthesis of ammonia (NH₃) from nitrogen (N₂) and hydrogen (H₂) is represented by the balanced chemical equation: N₂ (g) + 3H₂ (g) → 2NH₃ (g). Here, one mole of nitrogen reacts with three moles of hydrogen to form two moles of ammonia.
