The Chemical Earth The living and non-living components of the Earth contain mixtures 1 piss word and fit formulae of chemical substance reactions as they are encountered A balanced chemical equality must rush the same number of atoms of to each one element on each spot of the arrow. To balance a chemical compare: 1. carry through 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. equilibrise the equation by putting total in social movement of symbols or formulae: start with atoms that occur in one ordinate only on each side of the equation. 4. Add submit 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 altogether expose of one suit of atom. I.e. Diamond, Hydrogen Gas, Nit rogen Gas, etc. - A compound ! is anything made completely out of one fount 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 same musical theme throughout, for sheath pure water, sugar, aluminium, petrol or whisky - Heterogeneous means having non-uniform composition where we can see small pieces of the...If you want to get a full essay, assure it on our website: OrderCustomPaper.com
