3.1: CHEMICAL REACTION

• Chemical Reaction

  Process in which the bonds are broken within reactant molecules, and new bonds are formed within product molecules in order to form a new substance
• Physical change


  Change of state of the substance
• Chemical change


  A new substance is formed in which either energy is given off or absorbed
• Chemical changes are accompanied by certain physical changes
• Reactants


  Compounds that interact to produce new compounds
• Products


  The newly formed compounds
• Rate of reaction


  Depends on and is affected by factors like pressure, temperature, the concentration of reactants
• Chemical equation


  A mathematical statement which symbolizes the product formation from reactants while stating certain condition for which how the reaction has been conducted
• Types of Chemical Reactions


  • Combustion reaction
  • Decomposition reaction
  • Neutralization reaction
  • Redox Reaction
  • Precipitation or Double-Displacement Reaction
  • Synthesis reaction

  
• Combustion Reaction


  Combustible material reacts with an oxidizer to give an oxidized product
• Decomposition Reaction


  A single component breaks down into multiple products due to changes in energy like heat, light or electricity
• Neutralization Reaction


  Reaction between an acid and a base giving salt and water as the products
• Redox Reaction


  Reaction in which there is a transfer of electrons between chemical species
• Precipitation or Double-Displacement Reaction


  Two compounds react and their anions and cations switch places forming two new products
• Synthesis Reaction


  Multiple simple compounds combine under certain physical conditions giving out a complex product
