Chemical Reactions

Involves rearrangement of the molecular or ionic structure of a substance. Process in which one or more reactants are converted to one or more different products. Can be classified into five basic types. Analyzing reactants and products will allow placing it into one of these categories. Some reactions will fit into more than one category.

Learning Task 2:

  1. single displacement/single replacement
  2. decomposition
  3. synthesis/combination
  4. single displacement/single replacement
  5. combination/synthesis
  6. double replacement/double displacement
  7. double replacement/double displacement
  8. double displacement/double replacement
  9. single replacement/single displacement
  10. combustion

Types of Chemical Reactions:

  1. combination/synthesis
  2. decomposition
  3. single replacement/single displacement
  4. double replacement/double displacement
  5. combustion

A combination reaction, also known as a synthesis reaction, is a reaction in which two or more substances combine to form a single new substance. Combination reactions can also be called synthesis reactions. One combination reaction is two elements combining to form a compound.

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.

A single replacement reaction is a reaction in which one element replaces a similar element in a compound. A metal must be replaced by another metal while a non - metal must be replaced also by a non - metal.

A double replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. Double-replacement reactions generally occur between substances in aqueous solution. In order for a reaction to occur, one of the products is usually a solid precipitate, a gas, or a molecular compound such as water.

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve  O₂  as one reactant.
