The Chemical Earth The living and non-living components of the Earth contain mixtures 1 realise word and fit formulae of chemical substance reactions as they are encountered A balanced chemical equality must ask the same number of atoms of to each one element on each spot of the arrow. To balance a chemical equality: 1. deliver a word equation which includes all reactants and products. 2. Write the formulae for all the substances involved (to make pallid equation) by referring to the valences. 3. sense of balance the equation by putting total in preliminary of symbols or formulae: start with atoms that occur in one localise only on each side of the equation. 4. Add secernate 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 unaccompanied off of one suit of atom. I.e. Diamond, Hydrogen Gas, Nitrogen Gas, etcetera - A compound is anything made completely out of one event 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 furnish musical theme throughout, for sheat h pure water, sugar, aluminium, petrol or wh! isky - Heterogeneous means having non-uniform composition where we can name small pieces of the...If you want to get a full essay, auberge it on our website: OrderCustomPaper.com
