How to fill out limiting reactant and percent

How to fill out limiting reactant and percent:

1. Identify the balanced chemical equation for the reaction you are studying.
2. Determine the moles of each reactant present in the reaction.
3. Determine the stoichiometric ratio of the reactants by using the coefficients in the balanced equation.
4. Compare the stoichiometric ratio to the actual ratio of moles present. The reactant that is present in a lower ratio compared to what is needed is the limiting reactant.
5. Calculate the moles of the desired product that can be formed using the limiting reactant.
6. Convert the moles of the desired product to a mass or volume, if desired, using the molar mass or molar volume.
7. Calculate the percent yield by dividing the actual yield (obtained experimentally) by the theoretical yield (calculated from the stoichiometry) and multiplying by 100.

Who needs limiting reactant and percent:

1. Students studying chemistry or taking chemistry courses need to understand the concept of limiting reactant and percent.
2. Scientists and researchers in various fields such as pharmaceuticals, materials science, and environmental science utilize the concept of limiting reactant and percent in their experiments and analyses.
3. Industrial chemists and engineers working in production processes need to determine the limiting reactant and percent yield to optimize their manufacturing processes and reduce waste.
