FLASHCARD QUESTION

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.

2.

FLASHCARD QUESTION

Front

How do you identify the limiting reactant in a reaction?

Back

To identify the limiting reactant, calculate the moles of each reactant and determine which one produces the least amount of product based on the stoichiometry of the reaction.

3.

FLASHCARD QUESTION

Front

What is theoretical yield?

Back

Theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, calculated using stoichiometry.

4.

FLASHCARD QUESTION

Front

What is actual yield?

Back

Actual yield is the amount of product that is actually obtained from a chemical reaction, which may be less than the theoretical yield due to various factors.

5.

FLASHCARD QUESTION

Front

What is percent yield?

Back

Percent yield is a measure of the efficiency of a reaction, calculated as (actual yield / theoretical yield) x 100%.

6.

FLASHCARD QUESTION

Front

What is the mole ratio in a chemical reaction?

Back

The mole ratio is the ratio of the coefficients of reactants and products in a balanced chemical equation, used to convert between moles of different substances.

7.

FLASHCARD QUESTION

Front

How do you calculate percent yield?

Back

Percent yield = (actual yield / theoretical yield) x 100%.
