Question 1

mole ratio

Answer 1

The mole ratio allows us to convert from moles of one substance in a balanced equation to moles of a second substance in the equation
–Use the coefficients in the balanced equation to determine the mole ratio(s)

Question 2

limiting reactant

Answer 2

The reactant that runs out first and thus limits the amounts of products that can form.

Question 3

theoretical yield

Answer 3

Amount of product predicted from the amounts of reactants used.

Question 4

percent yield

Answer 4

actual yield of a product expressed as a percentage

actual yield/theoretical yield

Question 5

stoichiometry

Answer 5

the process of using a chemical equation to calculate the relative masses of reactants and products involved in a reaction.
