Investigation 7 Review - Stoichiometry - Enriched

Front

What is percent yield in a chemical reaction?

Back

Percent yield is the ratio of the actual yield of a product to the theoretical yield, expressed as a percentage. It indicates the efficiency of a reaction.

Front

How do you calculate percent yield?

Back

Percent Yield = (Actual Yield / Theoretical Yield) x 100%

Front

What is the theoretical yield?

Back

Theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, based on stoichiometric calculations.

Front

What is the mole ratio in a balanced chemical equation?

Back

The mole ratio is the ratio of moles of one substance to the moles of another substance in a balanced chemical equation, used to convert between moles of reactants and products.

Front

In the reaction 3 Mg + 1 Fe2O3 → 3 MgO + 2 Fe, what is the mole ratio of MgO to Fe?

Back

The mole ratio of MgO to Fe is 3 mol MgO / 2 mol Fe.

Front

What is the actual yield in a chemical reaction?

Back

Actual yield is the amount of product that is actually obtained from a chemical reaction, measured in the laboratory.

Front

What is the difference between actual yield and theoretical yield?

Back

Actual yield is what you obtain from an experiment, while theoretical yield is what you expect to obtain based on stoichiometry.

Front

How do you determine the limiting reactant in a chemical reaction?

Back

The limiting reactant is the reactant that is completely consumed first in a reaction, limiting the amount of product formed. It can be determined by comparing the mole ratios of reactants.

Front

What is stoichiometry?

Back

Stoichiometry is the calculation of reactants and products in chemical reactions based on the conservation of mass and the mole concept.

Front

Using the equation Fe2O3 + 3H2 → 2Fe + 3H2O, how many moles of iron can be produced from 6 moles of H2?

Back

4 moles of iron can be produced from 6 moles of H2.
