Transcript:What Are Types of Chemical Reactions
Today we'll be going over the different types of chemical reactions.
Chemical Reactions: Synthesis
A synthesis reaction occurs when two or more elements or compounds combine and create a new and more complex product (A+B--->C). An example of a synthesis reaction is the combination of sulfur and iron to form iron sulfide.
Chemical Reactions: Decomposition
A decomposition reaction is one where a compound breaks down into smaller and less complex elements or compounds (AB--->A+B or ABC--->A+B+C). An example of a decomposition reaction is the electrolysis of water to make oxygen and hydrogen gas.
Chemical Reactions: Single Displacement
A displacement reaction is a reaction where an element replaces, or displaces, a less active element in a compound. Iron will replace copper in a copper II chloride solution, producing iron II chloride and copper.
Chemical Reactions: Double Displacement
A double displacement reaction is a reaction where two compounds react and form new compounds. The formation of more stable compounds, such as of a water or a precipitate, powers these reactions (AB+CD--->AD+CB). Barium nitrate and sodium sulfate will form barium sulfate, the precipitate, and sodium nitrate.
Chemical Reactions: Combustion
A combustion reaction is an exothermic reaction that occurs when oxygen and another element or compound are combined. A basic combustion reactions occurs when carbon in the form of charcoal reacts with oxygen to form carbon dioxide and heat.
