1. The chemical Earth2 1.The life history and non-living comp unitynts of the Earth contain mixtures2 2.Although ab proscribed elements be found in combinations on Earth, some elements ar found uncombined5 3.Elements in Earth materials are endue generally as compounds because of interactions at the moteic level5 4. animation is required to extract elements from their naturally occurring sources7 5.The properties of elements and compounds are determined by their bonding structure8 Skills Summary/Outline10 1. The Chemical Earth The living and non-living components of the Earth contain mixtures 1 rebuild word and fit formulae of chemical substance reactions as they are encountered A balanced chemical equality must guide the same number of atoms of to each one element on each spot of the arrow. To balance a chemical equality: 1. drop a line a word equation which includes all react ants and products. 2. Write the formulae for all the substances involved (to make pallid equation) by referring to the valences. 3. proportionality the equation by putting total in wait of symbols or formulae: start with atoms that occur in one stead only on each side of the equation. 4. Add put forward symbols, (s), (l), (g), (aq).

2 Identify the difference in the midst of elements, compounds and mixtures in terms of particle theory - An element is anything made alone(predicate) out of one suit of atom. I.e. Diamond, Hydrogen Gas, Nitrogen Gas, and so on - A compound is anything made c! ompletely out of one lineament of particle composed of more than one type of atom chemically bonded. I.e. H2O, CO2, HCl, H2SO4 - A mixture is anything made out of many types of atoms. I.e., whiskey, crude oil - Homogeneous means of like musical theme throughout, for sheath pure water, sugar, aluminium, petrol or whisky - Heterogeneous means having non-uniform composition where we can come small pieces of the...If you want to get a full essay, pasture it on our website: OrderCustomPaper.com
