Balancing+Equations

Word Equation: When only the words of the reactants and products are given for an equation. Coefficients: Numbers before the compounds. State Symbols: (s), (l), (g) Reactants: Compounds on the left of the equation. Products: Compounds on the right of the equation. Law of Conversation of Mass: A fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system. Combustion: Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can result in the production of light in the form of either glowing or a flame. Single Replacement:  A + BC -> AB + C Double Replacement: AB + CD -> AD + CB Synthesis: A + B -> AB Decomposition: AB -> A + B Acid-Base Replacement: AB + CD -> AD + CB. One product must be water. Activity Series: Reference chart for single replacement reaction. Hydrocarbons: A compound of hydrogen and carbon, such as any of those that are the chief components of petroleum and natural gas Soluble: Dissolves in water. Insoluble: Doesn't dissolve in water. Precipitate: Solubiltity Rules: All common compounds of Group I and ammonium ions are soluble. All nitrates, acetates, and chlorates are soluble. All binary compounds of the halogens (other than F) with metals are soluble, except those of Ag, Hg(I), and Pb. Pb halides are soluble in hot water.) All sulfates are soluble, except those of barium, strontium, calcium, lead, silver, and mercury (I). The latter three are slightly soluble. Except for rule 1, carbonates, hydroxides, oxides, silicates, and phosphates are insoluble. Sulfides are insoluble except for calcium, barium, strontium, magnesium, sodium, potassium, and ammonium. Alpha: A helium nucleus emitted by some radioactive substances, originally regarded as a ray. Beta: A fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray.). Gamma: Electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength Nuclide: Background Radiation: The uniform microwave radiation remaining from the Big Bang NaOH + H2SO4 -> Na2SO4 + H2O 2 NaOH + H2SO4 -> Na2SO4 + H2O
 * __Directions:__**
 * a) list and define all vocabulary from the chapter**
 * b) type at least 4 sample problems with step-by-step directions of how to solve the problem; list the correct answers (if your chapter doesn't have math, there are still problems and concepts we learned.)**

__FeCl__ __3__ __+__ Be 3 (PO 4 ) 2 --> __BeCl__ __2__ __+__ FePO 4 2 FeCl 3 + 1 Be 3 (PO 4 ) 2 --> 3 BeCl 2 + 2 FePO 4

__AgNO__ __3__ __+__ LiOH --> __AgOH +__ LiNO 3 1 AgNO 3 + 1 LiOH --> 1 AgOH + 1 LiNO 3

__CH__ __4__ __+__ O 2 --> __CO__ __2__ __+__ H 2 O 1 CH 4 + 2 O 2 --> 1 CO 2 + 2 H 2 O http://misterguch.brinkster.net/eqnbalance.html http://www.sciencegeek.net/Chemistry/taters/EquationBalancing.htm http://phet.colorado.edu/en/simulation/balancing-chemical-equations
 * c) link at least 3 websites for additional resources to help with studying**

LEQ: How can you write a balanced chemical equation? Create and balance a chemical equation.
 * d) develop your own LEQ questions for the section - what did you think were the key points we learned?**


 * e) Once your page is done, visit 4 other chapters and answer their LEQ's. (This can be done on a separate piece of paper.)**
