Five Chemical Reactions

The five chemical reactions are

• Synthesis- is when two or more substances combine to form another more complicated substance 
• Decomposition- Opposite of synthesis, One substance breaks down into two or more simpler substances
• Single Displacement- Occurs when one element replaces another element in a compound
• Double Displacement- Two different atoms in two different compounds exchange places
• Combustion- A hydrocarbon reacts with oxygen, the products of combustion are always water + carbon dioxide 

Synthesis- when we lit the steel wool on fire
Fe+O2+-->Fe2+ O3

Displacement- nail in copper sulfate
Fe+CuSo4--> Cu + Fe2(So4)3
