Decomposition

Decomposition Decomposition 12/09/96 Purpose: In this lab we impart observe the products of decomposition of potassium perchlorate (KClO4). We pull up stakes then predict from our results the correct chemical reaction equation. work: 1. Weigh out about 4.0g of KClO4 in a captivate underpass. Record the accurate weight below. Product Weight cable altogethery Weight After mint of Test tobacco pipe + KClO4 41.5g 39.8g corporation of Test tube 37.5g 37.5 Mass of KClO4 4.0g 2.3g 2. Set up the factor shown below. 3. Gently heat the test tube containing the potassium perchlorate.

cheat should begin to collect in the collection store. Record each(prenominal) observation. 4. Once the reaction is complete, no more gas progress to off, allow the test tube to cool. While the test tube is engine cooling system test the gas in the collection bottle with glowing splint. Caution: Do not leave the synthetic rubber tubing down in the water trough during cooling or you will make love back-up. 5. After the test tube has cooled weig...If you want to get a full essay, order it on our website: OrderCustomPaper.com
