4  Pages. Obtain a piece of copper wire and weigh it to the nearest.

Try not to transfer the blue precipitate onto the litmus paper: that will result in some loss of copper, and a possibly false blue on the litmus paper. n  Combustion– An element reacts with oxygen to form an oxide (this is also a Synthesis) A compound consisting of carbon, hydrogen and/or oxygen (C8H18is called octane) reacts with oxygen to form carbon dioxide and water.

Premium Chemistry Department UCC Petroleum, Sulfuric acid, Filter paper 654  Words | A Cycle of Copper Reactions The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder.

Experiment 3 The reaction between Cu and HNO3 produces NO2, a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas.
