Question

1. What is the chemical formula for the limiting reactant in the reaction shown?

chemical formula: ?

Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

chemical equation: ?

Answer 1

NO is reacting with H₂ to produce N₂ + H₂O.

The figure indicates that all four of the NO molecules have reacted, but one of the five H₂ molecules remains unreacted. So H₂ is in excess, and NO is the limiting reactant.

For NO + H₂ → N₂ + H₂O the balanced chemical equation for the reaction is

2 NO + 2 H₂ → N₂ + 2 H₂O
