elements and compounds found in mixtures that make up earth materials. Applying appropriate models‚ theories and laws of chemistry to the range of earth materials allows a useful classification of the materials and a better understanding of the properties of substances. This module increases students’ understanding of the nature‚ practice‚ applications and uses of chemistry. Outcomes: 8.2.1 The living and non-living components of the Earth contain mixtures .2.1 a) Construct word and balanced

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules
