We’re being asked to determine the limiting reactant in the following reaction:
CH4 + 2 O2 → CO2 + 2 H2O (the reaction is balanced)
To determine the limiting reactant, we need to determine which is the reactant that forms the less amount of product.
This is because once the limiting reactant is all used up, the reaction can no longer proceed and make more products. This means the limiting reactant determines the maximum mass of the product (CO2) formed.
When 85.0 g of CH4 are mixed with 16.0 g of O2 the limiting reactant is
CH4 + 2 O2 → CO2 + 2 H2O
