How to fill out limiting reactant and yield

To fill out the limiting reactant and yield, you can follow these steps:

1. Identify the balanced chemical equation: Start by writing down the balanced chemical equation for the reaction you are studying. This equation shows the relative amounts of reactants and products involved in the reaction.
2. Determine the molar ratios: From the balanced equation, determine the molar ratio between the limiting reactant and the product you are interested in calculating the yield for. This ratio is derived from the coefficients of the balanced equation.
3. Calculate the moles of each reactant: Using the known quantities of the reactants, calculate the number of moles for each reactant involved in the reaction. This step requires using the molar mass of each substance.
4. Identify the limiting reactant: Compare the moles of each reactant calculated in the previous step to determine which reactant is limiting in the reaction. The limiting reactant is the one that is completely consumed and determines the maximum amount of product that can be formed.
5. Calculate the theoretical yield: Once the limiting reactant is identified, use the molar ratio from step 2 to calculate the theoretical yield of the desired product. The theoretical yield represents the maximum amount of product that can be obtained if the reaction goes to completion.
6. Calculate the percent yield: If you have performed a reaction in the laboratory, you can calculate the percent yield by dividing the actual yield (the amount of product obtained in the experiment) by the theoretical yield, and then multiplying by 100.

Who needs limiting reactant and yield?
