The 6 Main Types of Chemical Reactions are: synthesis reaction decomposition reaction single displacement reaction double displacement reaction combustion reaction acid-base reaction
Example: Combustion Reactions A combustion reaction occurs when a substance reacts quickly with oxygen (O2). Combustion is commonly called burning. The substance that burns is usually referred to as fuel. The products of a combustion reaction include carbon dioxide (CO2) and water (H2O). The reaction typically gives off heat and light as well. The general equation for a combustion reaction can be represented by: Fuel + O2 -> CO2 + H2O The fuel that burns in a combustion reaction is often a substance called a hydrocarbon. A hydrocarbon is a compound that contains only carbon (C) and hydrogen (H). Fossil fuels, such as natural gas, consist of hydrocarbons. Natural gas is a fuel that is commonly used in home furnaces and gas stoves. The main component of natural gas is the hydrocarbon called methane (CH4).
The combustion of methane is represented by the equation: CH4 + 2O2 -> CO2 + 2H2O Your own body cells burn fuel in combustion reactions. The fuel is glucose (C6H12O6), a simple sugar. The process in which combustion of glucose occurs in body cells is called cellular respiration. This combustion reaction provides energy for life processes.
Cellular respiration can be summed up by the equation: C6H12O6 + 6O2 -> 6CO2 + 6H2O
