Which process is characterized by the combination of a substance with oxygen to produce heat and light?

• A. Oxidation
• B. Decomposition
• C. Combustion
• D. Reduction

Answer: (C)

The process characterized by the combination of a substance with oxygen to produce heat and light is combustion. During combustion, a fuel reacts with oxygen, resulting in a chemical reaction that releases energy in the form of heat and light. This reaction is typically evident in everyday life, such as when wood burns in a fireplace or when gasoline combusts in an engine. Combustion is essential in various applications, from heating and cooking to powering vehicles and generating electricity. The presence of oxygen is a crucial factor in this process, as it enables the oxidation of the fuel, leading to the release of energy. While oxidation involves the reaction of a substance with oxygen, it does not inherently produce heat and light in the same way combustion does. Decomposition refers to the breakdown of compounds into simpler substances, and reduction involves the gain of electrons or a decrease in oxidation state, which are distinct from combustion's focus on energy release through a reaction with oxygen.
