Stoichiometry Review

Front

What is percent yield?

Back

Percent yield is a measure of the efficiency of a chemical reaction, calculated as the ratio of the actual yield to the theoretical yield, multiplied by 100.

Front

What is actual yield?

Back

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

Front

How can the concentration of a mixture be increased?

Back

The concentration of a mixture can be increased by adding more solute (e.g., powder) to the mixture.

Front

What is theoretical yield?

Back

Theoretical yield is the maximum amount of product that could be obtained from a chemical reaction, based on the balanced equation.

Front

What is the first step in solving a stoichiometry problem?

Back

The first step in solving a stoichiometry problem is to write a balanced chemical equation.

Front

Define mole ratio.

Back

Mole ratio is the ratio of the coefficients of any two substances in a balanced chemical equation, used to convert between moles of reactants and products.

Front

What is the difference between theoretical yield and actual yield?

Back

Theoretical yield is the calculated maximum amount of product, while actual yield is the amount of product actually obtained from the reaction.

Front

What is a balanced equation?

Back

A balanced equation is a chemical equation in which the number of atoms for each element is the same on both sides of the equation.

Front

What does it mean to calculate percent yield?

Back

Calculating percent yield involves determining how much product was actually produced compared to how much could have been produced theoretically.

Front

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

Back

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