Unit 07 Stoichiometry Part II Recovery Flashcardizz 5th Period

Front

What is a limiting reactant?

Back

The limiting reactant is the substance that is completely consumed in a chemical reaction, limiting the amount of product that can be formed.

Front

What is theoretical yield?

Back

Theoretical yield is the maximum amount of product that can be produced in a chemical reaction based on the amounts of reactants used.

Front

What is actual yield?

Back

Actual yield is the amount of product that is actually obtained from a chemical reaction.

Front

What is percentage yield?

Back

Percentage yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage.

Front

What is a mole ratio?

Back

A mole ratio is the ratio of the coefficients of any two substances in a balanced chemical equation.

Front

What is the balanced equation for the formation of water from hydrogen and oxygen?

Back

2 H₂ + O₂ → 2 H₂O.

Front

How do you determine the limiting reactant in a reaction?

Back

To determine the limiting reactant, calculate the amount of product each reactant can produce and identify the one that produces the least amount.

Front

What is the significance of the limiting reactant in a chemical reaction?

Back

The limiting reactant determines the maximum amount of product that can be formed in a reaction.

Front

What is the formula for calculating percentage yield?

Back

Percentage Yield = (Actual Yield / Theoretical Yield) × 100.

Front

What is the role of stoichiometry in chemical reactions?

Back

Stoichiometry allows chemists to predict the quantities of reactants and products involved in a chemical reaction.
