Stoichiometric calculations help us find out which reactant is the limiting reactant in a chemical reaction.
A limiting reactant is the substance that runs out first. This means it decides how much product we can make.
Balanced Chemical Equation: First, we need a balanced equation. For example:
Molar Ratios: Use the numbers in front of the chemicals (called coefficients) from the balanced equation to find the ratios. If ( a = 2 ) and ( b = 3 ), then the ratio of ( A ) to ( B ) is .
Convert to Moles: Change the weight or volume of each reactant into moles using their molar masses. This means using their specific weights to see how many parts we have.
Determine Limiting Reactant: Now, compare the mole ratios of what you have to what you need. The reactant that can make the least amount of product is the limiting reactant.
By doing these steps, you can predict how much product you will make and improve your reactions.
