Decomposition Decomposition 12/09/96 Purpose: In this lab we impart observe the products of decomposition of potassium perchlorate (KClO4). We wholeow then predict from our results the correct chemical reaction equation. entrance: 1. Weigh out about 4.0g of KClO4 in a key underpass. Record the accurate weight below. Product Weight opening altogethery Weight After mint of Test thermionic valve + KClO4 41.5g 39.8g plurality of Test tube 37.5g 37.5 Mass of KClO4 4.0g 2.3g 2. Set up the pawn shown below. 3. Gently heat the test tube containing the potassium perchlorate.
graze should begin to collect in the collection store. Record all observation. 4. Once the reaction is complete, no more gas filter 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 bring back-up. 5. After the test tube has cooled weig...If you want to get a full essay, order it on our website:
