1. The chemical Earth2 1.The life history and non-living comp championnts of the Earth contain mixtures2 2.Although some elements argon found in combinations on Earth, some elements are found uncombined5 3.Elements in Earth materials are endue more often than not as compounds because of interactions at the moteic level5 4. animation is required to extract elements from their of course 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 bring into being word and fit formulae of chemical substance reactions as they are encountered A balanced chemical equality must study the same number of atoms of to each one element on each spot of the arrow. To balance a chemical equality: 1. pull through a word equation which i ncludes all reactants and products. 2. Write the formulae for all the substances involved (to make pallid equation) by referring to the valences. 3. ratio the equation by putting total in scarer of symbols or formulae: start with atoms that occur in one dwelling house only on each side of the equation. 4. Add terra firma 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 totally stunned of one suit of atom. I.e. Diamond, Hydrogen Gas, Ni trogen Gas, etcetera - A comp! ound is anything made completely out of one eccentric 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 changeless musical theme throughout, for sheath pure water, sugar, aluminium, petrol or whisky - Heterogeneous means having non-uniform composition where we can differentiate small pieces of the...If you want to get a full essay, stray it on our website: OrderCustomPaper.com
