Show hintHide hint
Think about which reactant runs out first.
Question 2.
What is the formula for percent yield?
Show hintHide hint
Remember, actual yield comes from your experiment.
3Question 3.
What is a limiting reagent?
- The reactant that is completely consumed
- The reactant in excess
- The one that produces the most product
Show hintHide hint

Consider losses during a reaction.
Question 5.
In a reaction where 3.0 moles of A and 5.0 moles of B produce a product C according to the equation A + 2B → C, identify the limiting reagent and calculate the theoretical yield of C if the molar mass of C is 50 g/mol.
