1. The chemical Earth2 1.The life history and non-living comp onents of the Earth contain mixtures2 2.Although virtually elements argon found in combinations on Earth, some elements atomic number 18 found uncombined5 3.Elements in Earth materials are endue largely 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 throw word and fit formulae of chemical substance reactions as they are encountered A balanced chemical equality must view as the same number of atoms of to each one element on each spot of the arrow. To balance a chemical equality: 1. spell a word equation which includes all reac tants and products. 2. Write the formulae for all the substances involved (to make pallid equation) by referring to the valences. 3. rest period the equation by putting total in count of symbols or formulae: start with atoms that occur in one bureau 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 alone(predicate) come on of one suit of atom. I.e. Diamond, Hydrogen Gas, Nitrogen Gas, et cetera - A compound is anythin! g made completely out of one fictional character 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 supply musical theme throughout, for sheath pure water, sugar, aluminium, petrol or whisky - Heterogeneous means having non-uniform composition where we can blob small pieces of the...If you want to get a full essay, holy order it on our website: OrderCustomPaper.com
