Transcript of "Types of chemical reactions"

  1. 1. Types of Chemical Reactions
  2. 2. Five Types of Chemical Reactions • Synthesis • Decomposition • Single Replacement • Double Replacement • Combustion
  3. 3. Synthesis• The word synthesis means to put things together to make a whole.• In a synthesis reaction, two or more substances combine to form a single new substance.• The general formula for a synthesis reaction is: A + B AB
  4. 4. SynthesisSynthesis reactions are easy to recognize. There will be twoor more reactants, but only one product. Below are someexamples of synthesis reactions. 2H2+ O2 2H2O CO2 + H2O H2CO3 MgO + H2O Mg(OH)2 2Na + Cl2 2NaCl
  5. 5. Decomposition• The word decomposition means to separate or breakdown into smaller pieces.• In a decomposition reaction, one substance breaks down into two or more products. It is really a synthesis reaction in reverse.• The general formula for a decomposition reaction is: AB A + B
  6. 6. DecompositionIn order to identify decomposition reactions, look for chemicalequations which have only one reactant, but two or moreproducts. Below are some examples of synthesis reactions. 2NaHCO3 2CO2 + H2O + Na2O CuCO3 CO2 + CuO 2H2O2 O2 + 2H2O H2SO4 H2O + SO3
  7. 7. Single Replacement• In a single replacement reaction, one element replaces another element in a compound.• The general formula for a single replacement reaction is: A + BC B + AC
  8. 8. Single ReplacementSingle replacement reactions have an element and acompound on both the reactant and product side of theequation. Below are some examples of synthesis reactions. Fe + CuSO4 FeSO4 + Cu2NaBr + Cl2 2NaCl + Br2 Mg + H2O MgO + H2
  9. 9. Double Replacement• In a double replacement reaction, a compound reacts with another compound to form two new compounds.• The general formula for a single replacement reaction is: AB + CD AD + BC
  10. 10. Double ReplacementDouble replacement reactions have two compounds on boththe reactant and product side of the equation. Below are someexamples of synthesis reactions. HCl + NaOH NaCl + H2O KOH + H2SO4 K2SO4 + H2O AgNO3 + NaCl AgCl + NaNO3
  11. 11. Combustion• Combustion, or burning, is a chemical reaction between an organic compound (usually a hydrocarbon) and oxygen gas.• The products in a combustion reaction are carbon dioxide and water.• Combustion reactions are exothermic, meaning that they produce heat.• The general formula for a combustion reaction is: CxHx + O2 CO2 + H2O
  12. 12. CombustionCombustion reactions always have oxygen gas as a reactantand water and carbon dioxide as products. Below are someexamples of combustion reactions. CH4 + 2O2 CO2 + 2H2O 2C4H10 + 13O2 8CO2 + 10H2O CH3OH + O2 CO2 + 2H2O
