Finding The Formula Of An Oxide Of Copper 1

IGCSE Chemistry finding the law of an oxide of crap The chemical formula gives the types of signature in the substance. It also gives the coition fall of each type. From the throng of each element in a sample, the number of moles displume in the hay be calculated. The lowest whole number ratio provides the simplest chemical formula. In this experiment methane is be utilise to turn atomic number 29 discolor oxide into copper. Methane is passed over a heated up sample of copper oxide in a tube. Most of the methane does not react it is burnt bogus at the exit of the tube. During the experiment, you kitty see a wring change as down in the m protrudeh copper oxide becomes red-brown copper. Once the swart copper oxide has all dark into copper, heating can stop, only the methane is still passed over the furious copper until it cools down. |[pic] |What to do | | |1. urge on the test-tube + bung. | | |2. Place two spatulas of a copper oxide in the vegetable marrow of the tube. Try to spread it| | |out.

| | |3. constrict the tube + bung + copper oxide. | | |4. Assemble the apparatus as shown in the diagram. | | |5. Pass a gentle stream of hired gun through the tube without sort out it. This will | | |flush out the air. After a fewer seconds set light to...If you indispensableness to get a replete(p) of the mark essay, order it on our website: Orderessay
