Section 1.4 CHEMICAL CHANGES - REACTIONS - reactants and products Heating iron and sulphur is classic chemistry experiment to illustrate what is meant by CHEMICAL CHANGE and you can adapt the general conclusions described at the end of this section to any chemical reaction. A mixture of silvery grey iron filings and yellow sulphur powder is made. The iron can be plucked out with a magnet i.e. an easily achieved physical separation because the iron and sulphur are not chemically combined yet! They are still the same iron and sulphur. However, on heating the mixture, it eventually glows red on its own and a dark grey solid called iron sulphide is formed. gcse definitions Atom element molecule compounds pure impure mixture, meaning definitions physical change, evidence of chemical change explained explaining KS3 science KS4 science GCSE IGCSE O Level chemistry revision notes gcse definitions Atom element molecule compounds pure impure mixture, meaning definitions physical change, evidence of chemical change explained explaining KS3 science KS4 science GCSE IGCSE O Level chemistry revision notes
