Answer the following question given this paragraph: A combustion reaction occurs when a substance reacts quickly with oxygen (O 2 ). You can see an example of a combustion reaction in Figure below . Combustion is commonly called burning. The substance that burns is usually referred to as fuel. The products of a combustion reaction include carbon dioxide (CO 2 ) and water (H 2 O). The reaction typically gives off heat and light as well. The general equation for a combustion reaction can be represented by:. Q: What occurs when a substance reacts quickly with oxygen? Choices: - convection - oxidation - catalytic conversion - combustion reaction A:
combustion reaction
