Decomposition

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

bumble should begin to collect in the collection store. Record all told observation. 4. Once the reaction is complete, no more gas give 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 non leave the synthetic rubber tubing down in the water trough during cooling or you will meet 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
