Product Description
Students will heat potassium chlorate over a Bunsen burner until constant mass is achieved. The gas released will be tested with a glowing splint. Students will use the data collected to write the balanced chemical equation and determine the experimental mass of oxygen produced. They will also use stoichiometry to determine the theoretical amount of oxygen which should have been produced. Percent yield and percent error is also calculated.

Included is a supplementary worksheet (with answers) based on a synthesis reaction.

Students can also follow the video at http://www.youtube.com/watch?v=7pCIA5YBi3E and complete the worksheet if they miss the lab activity.
