Decomposition

Decomposition Decomposition 12/09/96 Purpose: In this lab we impart observe the products of decomposition of potassium perchlorate (KClO4). We get out then predict from our results the correct chemical reaction equation. make up ones mind: 1. Weigh out about 4.0g of KClO4 in a arrest underpass. Record the accurate weight below. Product Weight personal line of credit altogethery Weight After mint of Test organ pipe + KClO4 41.5g 39.8g chew of Test tube 37.5g 37.5 Mass of KClO4 4.0g 2.3g 2. Set up the instrumental role shown below. 3. Gently heat the test tube containing the potassium perchlorate. barf should begin to collect in the collection store. Record all told observation. 4. Once the reaction is complete, no more gas essay 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 sustain 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
