Front

What is theoretical yield?

Back

The maximum amount of product that could be obtained from a chemical reaction based on the balanced equation.

Front

What is the limiting reactant?

Back

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

Front

How do you calculate percent yield?

Back

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

Front

What is actual yield?

Back

The amount of product actually obtained from a chemical reaction.

Front

What is a mole ratio?

Back

The ratio of moles of one substance to the moles of another substance in a balanced chemical equation.

Front

In the reaction 4NH3 + 6NO -> 5N2 + 6H2O, if you have 10 moles of NH3 and 30 moles of NO, which is the limiting reactant?

Back

NH3 is the limiting reactant.

Front

In the reaction of Na with Cl2, if the theoretical yield is 13 grams and the actual yield is 12.5 grams, what is the percent yield?

Back

The percent yield is 96%.

Front

What does it mean if a reactant is in excess?

Back

It means there is more of that reactant than is needed to completely react with the limiting reactant.

Front

What is the significance of a balanced chemical equation?

Back

It shows the conservation of mass and the ratio of reactants to products.

Front

What is the role of coefficients in a balanced equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction.
