Exploring Limiting Reactants in Stoichiometry

What term describes the reactant that is completely consumed first in a reaction?

• Theoretical yield

• Excess reactant

• Percent yield

• Limiting reactant

In the turkey sandwich example, what is used to calculate the number of sandwiches that can be made?

• Number of mayo servings

• Number of turkey slabs

• Type of bread used

• Mole bridges

In the context of the turkey sandwich example, what does the mayo represent?

• Limiting reactant

• Actual yield

• Excess reactant

• Theoretical yield

What does the percent yield measure in a stoichiometry problem?

• The efficiency of reactant usage

• The ratio of actual yield to theoretical yield multiplied by 100

• The difference between the theoretical and actual yields

• The amount of excess reactant left

Which reactant determines the amount of product formed in a stoichiometry problem?

• Excess reactant

• Limiting reactant

• Actual reactant

• Theoretical reactant

What is the role of a balanced equation in stoichiometry?

• To calculate the percent error

• To provide the exact quantities of reactants needed

• To show the relationship between reactants and products

• To determine the type of chemical reaction

What does the theoretical yield represent in a chemical reaction?

• The maximum possible amount of product obtainable

• The efficiency of the reaction

• The amount of reactants used

• The actual amount of product obtained

What is the significance of the mole ratio in stoichiometry calculations?

• It is used to convert between moles of reactants and products

• It indicates the purity of reactants

• It determines the type of products formed

• It helps in balancing the chemical equation

How is the excess reactant quantity determined after a reaction?

• By measuring the reactant left physically

• By calculating the theoretical yield

• By subtracting the used amount from the initial amount

• By adding the used amount to the product formed

What happens when the limiting reactant is completely consumed in a reaction?

• The reaction stops

• The reaction speeds up

• The theoretical yield is recalculated

• The excess reactants are also consumed
