IGCSE Chemistry finding the convention of an oxide of crap The chemical formula gives the types of tinge in the substance. It also gives the relative subject of sever all toldy type. From the plurality of each element in a sample, the number of moles roll in the hay be calculated. The lowest all in all number ratio provides the simplest chemical formula.

During the experiment, you can see a distort change as macabre copper oxide becomes red-brown copper. Once the black copper oxide has all 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.
