Chemical Reactions Lu Na Wang, Hailey Gipson, A.J. Whisenant

Synthesis - Chemical reaction in which two or more substances react to yield a single product.

Examples of Synthesis

  • Formation of binary compound : A + B --> AB
  • Metal oxide-water reactions : MO + H2O --> base
  • Nonmetal oxide-water reactions : (NM)O + H2O --> acid

Decomposition - A type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.

Examples of Decomposition

  • Binary Compounds : AB --> A + B
  • Metallic Carbonates : MCO3 --> MO + CO2
  • Metallic Hydrogen Carbonates : MHCO3 --> MO + H2O + CO2
  • Metallic Hydroxides : MOH --> MO + H2O
  • Metallic Chlorates : MCIO3 --> MCI + O2
  • Oxyacids Decompose to Nonmetal Oxides and Water : acid --> (NM)O + O2

Single Replacement - Chemical reaction that occurs when the atoms of one element replace the atoms of another element in a compound.

Examples of Single Replacement

  • Metal-Metal Replacement : A + BC --> AC + B
  • Active Metal Replaces H from Water : M + H2O --> MOH + H2
  • Active Metal Replaces H from Acid : M + HX --> MX + H2
  • Halide-Halide Replacement : D + BC --> BD + C

Double Replacement - A chemical reaction where two compounds react where the positive ions and the negative ions of the two reactants switch places, forming two new compounds or products.

Examples of Double Replacement

  • Formation of a Precipitate from Solution
  • Acid-Base Neutralization Reaction

Combustion Reaction - A chemical reaction that occurs when a substance reacts with oxygen releasing energy in the form of heat or light.

Example of Combustion

  • Hydrocarbon + Oxygen --> Carbon Dioxide + Water

How to use activity series :

  • Find if the metal above the other metal
  • If it is, then the metal can replace the metal in a reaction. If not, then the metal can NOT be replaced

How to use solubility rules:

  • Read the rules and see which one fits the elements you are using.Decide if element is soluble
  • If it is add (ag) to the end of the chemical symbol
  • If not, add (s) to the add of the chemical symbol
