I. Title Page Experiment 4 Limiting and Excess Reagents Date Performed: 2/8/11 Name: Kate McMillan Date Submitted: 2/16/11 Lab Partner: None CHM1045L 16 Yengjie Yu II. Purpose This experiment will help further the student’s recently learning explorations with stoichiometry. Students will learn how to calculate the product and reaction amounts using reaction stoichiometry. By giving different amounts of the product to different groups in the class, students will learn that it isn’t always obvious which reactant will be limiting and which will be excessive. III. Procedure The only differences from the procedure written in each student’s notebook and what was done during lab was a different cumulative table is given by the TA to record the
