Stoichiometry Flashcard - Lvl

Front

What is theoretical yield?

Back

The maximum amount of product that could be obtained from a chemical reaction based on the balanced equation.

Front

How do you balance a chemical equation?

Back

By ensuring that the number of atoms of each element is the same on both sides of the equation.

Front

What is actual yield?

Back

The measured amount of product obtained from a chemical reaction.

Front

What does a balanced chemical equation provide?

Back

The mole ratio of any two substances in the reaction.

Front

What is mole ratio?

Back

The ratio of moles of one substance to moles of another substance in a balanced chemical equation.

Front

How do you determine the mole ratio from a chemical equation?

Back

By using the coefficients in front of the chemical formulas in the balanced equation.

Front

What is the percentage yield?

Back

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

Front

What is the significance of the coefficients in a balanced equation?

Back

They indicate the relative amounts of reactants and products involved in the reaction.

Front

What is the mole ratio of H₂O to H₃PO₄ in the equation P₄O₁₀ + 6 H₂O → 4 H₃PO₄?

Back

6:4.

Front

What is a limiting reactant?

Back

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