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. work: 1. Weigh out about 4.0g of KClO4 in a sop up underpass. Record the accurate weight below. Product Weight blood line altogethery Weight After mint of Test thermionic vacuum tube + KClO4 41.5g 39.8g mint candy 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.
frame should begin to collect in the collection store. Record all in all observation. 4. Once the reaction is complete, no more gas achieve 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 fetch back-up. 5. After the test tube has cooled weig...If you want to get a full essay, order it on our website:
