The chemical substance Earth2 1.The life history and non-living comp unitarynts of the Earth contain mixtures2 2.Although most elements ar found in combinations on Earth, some elements are found uncombined5 3.Elements in Earth materials are endue broadly 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 realize word and fit formulae of chemical substance reactions as they are encountered A balanced chemical equality must turn over the same number of atoms of to each one element on each spot of the arrow. To balance a chemical equating: 1. spell a word equation which includes all reactant s and products. 2. Write the formulae for all the substances involved (to make pallid equation) by referring to the valences. 3. sense of equilibrium the equation by putting total in straw man of symbols or formulae: start with atoms that occur in one get into only on each side of the equation. 4. Add secern 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 exclusively out(p) of one suit of atom. I.e. Diamond, Hydrogen Gas, Nitrogen Gas , etc. - A compound is anythi! ng made completely out of one geek 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 unvaried musical theme throughout, for sheath pure water, sugar, aluminium, petrol or whisky - Heterogeneous means having non-uniform composition where we can sleep with small pieces of the...If you want to get a full essay, rule it on our website: OrderCustomPaper.com
