Combination or Synthesis | Two or more substances combine together to form one compound. |
Decomposition | A compound decomposes into two or more substances. |
Combustion | All elements combine with oxygen. The most common is the burning of a hydrocarbon (carbon and hydrogen only) to produce carbon dioxide and water. |
