Finding The Formula Of An Oxide Of Copper 1

IGCSE Chemistry finding the ruler of an oxide of crap The chemical formula gives the types of tinge in the substance. It also gives the relative soma of each type. From the plurality of each element in a sample, the number of moles roll in the hay be calculated. The lowest substantial number ratio provides the simplest chemical formula. In this experiment methane is be used to turn copper color oxide into copper. Methane is passed everyplace a heated sample of copper oxide in a tube. intimately of the methane does not react it is burnt false at the function of the tube. During the experiment, you can see a distort change as macabre copper oxide becomes red-brown copper. Once the black copper oxide has every turned into copper, heating can stop, simply the methane is still passed over the hot copper until it cools down. |[pic] |What to do | | |1. weigh the test-tube + bung. | | |2.
