What would be the limiting reagent if 26.0 grams of C3H9N were reacted with 46.3 grams of O2? 4C3H9N+25O2=>12CO2+18H2O+4NO2
The limiting reactant would be O₂.
The balanced equation for the reaction is
4C₃H₉N + 25O₂ →12CO₂ + 18H₂O + 4NO₂
To determine the limiting reactant, we calculate the amount of product that can be formed from each of the reactants. Whichever reactant gives the smaller amount of product is the limiting reactant.
Let's use CO₂ as the product.
26.0 g C₃H₉N ×
46.3 g O₂ ×
The O₂ gives the smaller amount of CO₂, so the O₂ is the limiting reactant.
Hope this helps.
