  2. Five Types Of Chemical Reactions Double Replacement or Displacement Reaction: In this chemical reaction, the cations and anions of two different substances switch their places to yield two totally different compounds. • Synthesis Reaction: In this reaction, two or more simple substances (reactants) combine together to yield a more complex substance. Decomposition Reaction: In this type of chemical reaction, a complex substance breaks down into some simple substances. A single reactant produces two or more products Single Replacement or Displacement Reaction: In this kind of reaction, a less active element is replaced by a more active element present in a compound. Two reactants produce two products Combustion: During this chemical reaction, a hydrocarbon is burnt in the presence of oxygen to form carbon dioxide (in complete combustion), or carbon monoxide (in partial combustion due to a limited amount of oxygen).

  3. Synthesis Reaction • A synthesis Reaction is when two or more simple substances come together to form a new substance • Example: H2O + O2 = 2H2O (Reactant + Reactant -------> product) The skinny bird (reactant) eats the worm (reactant) to become a fat bird (Product)

  4. Decomposition Reaction • Decomposition Reaction is the separation of a chemical compound into a simpler compounds (opposite of chemical synthesis) • Example: 2H2O -> 2H2 + O2 The egg (reactant), which had a turtle in it, now has opened and the turtle (product) and egg shell (product) are now two different things

  5. Single Replacement or Displacement Reaction • In a single replacement reaction a element that isn't combined with another is replaced by another element The guy in the orange shirt steals the other guys with the weird haircut’s date which is single replacement reaction

  6. Double Replacement or Displacement Reaction • In a double replacement reaction parts of two compounds switch places to makes two different new compounds Look how the presidents (reactants) switch hats to make two presidents (products) with different hats and this is Double Displacement

  7. Combustion • A combustion reaction is when all substances in a compound are combined with oxygen, which then produces carbon dioxide and water.
