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.

Front

How do you determine the limiting reactant in a reaction?

Back

To determine the limiting reactant, compare the mole ratio of the reactants used in the reaction to the mole ratio from the balanced equation.

Front

What is 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 actual yield?

Back

Actual yield is the amount of product that is actually obtained from a chemical reaction, which is often less than the theoretical yield.

Front

How do you calculate percent yield?

Back

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

Front

What is the mole ratio?

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.

Front

What is the significance of a balanced chemical equation?

Back

A balanced chemical equation ensures that the law of conservation of mass is followed, showing that the number of atoms of each element is the same on both sides of the equation.

Front

What happens if one reactant is in excess?

Back

If one reactant is in excess, it means that there is more of that reactant than needed to completely react with the limiting reactant.

Front

What is the role of stoichiometry in chemistry?

Back

Stoichiometry is used to calculate the quantities of reactants and products in chemical reactions, allowing chemists to predict yields and reactant needs.

Front

What is a balanced equation for the reaction of sodium and chlorine?

Back

2Na + Cl2 -> 2NaCl.
