Stoichiometry

Front

What are mole ratios?

Back

Mole ratios are the ratios of moles of one substance to moles of another substance in a balanced chemical equation.

Front

Where are mole ratios obtained from?

Back

Mole ratios are obtained from the balanced chemical equation.

Front

What is theoretical yield?

Back

Theoretical yield is the maximum amount of product that could be obtained in a chemical reaction.

Front

What is the first step to solve a stoichiometry problem?

Back

The first step is to write a balanced equation.

Front

What is a Limiting Reagent?

Back

A Limiting Reagent is the reactant that is completely consumed first in a chemical reaction.

Front

What is an Excess Reactant?

Back

An Excess Reactant is a reactant that remains after the reaction has gone to completion.

Front

What is the difference between actual yield and theoretical yield?

Back

Actual yield is the amount of product actually obtained from a reaction, while theoretical yield is the maximum possible amount.

Front

How do you determine the Limiting Reagent in a reaction?

Back

To determine the Limiting Reagent, compare the mole ratios of the reactants used in the balanced equation.

Front

What is the purpose of a balanced chemical equation in stoichiometry?

Back

A balanced chemical equation provides the mole ratios needed to calculate the amounts of reactants and products.

Front

What is the significance of mole ratios in stoichiometry?

Back

Mole ratios are used to convert between moles of reactants and products in a chemical reaction.
