- 20. EXAMPLE 1
- 22. REMEMBER 1. If the calculated MOLES NEEDED is greater than the GIVEN MOLES for a reactant, then that reactant is the limiting reactant. 2. If the calculated MOLES NEEDED is less than the GIVEN MOLES for a given reactant, then that reactant is the excess reactant.

- 30. SUMMARY – COMPLETE THE SENTENCE 1. Limiting reactant is the reactant that determines how much product can be made 2. A chemical reaction stops when the limiting reactant is used up. 3. A reactant that remains after a chemical reaction stops is called the excess. 4. If the calculated MOLES NEEDED is greater than the GIVEN MOLES for a reactant, then that reactant is the limiting reactant. 5. If the calculated MOLES NEEDED is less than the GIVEN MOLES for a given reactant, then that reactant is the excess reactant.
