Combustion:
* This is the most common reaction we think of when we talk about oxygen. Burning fuels like wood, oil, gas, or paper involves a rapid reaction with oxygen that releases heat and light.
* The general formula is: fuel + oxygen → carbon dioxide + water + energy
Oxidation:
* This is a broader term for any chemical reaction involving the loss of electrons. Oxygen often acts as the oxidizing agent, accepting electrons from other substances.
* Examples:
* Rusting: Iron reacts with oxygen and water to form iron oxide (rust).
* Food Spoilage: Oxygen can react with fats and oils in food, leading to rancidity.
* Respiration: Living organisms take in oxygen and use it to break down sugars for energy.
Other Reactions:
* Formation of Oxides: Many elements combine with oxygen to form oxides. For example, sodium reacts with oxygen to form sodium oxide.
* Chemical Synthesis: Oxygen is used as a reactant in the production of many chemicals and materials, like sulfuric acid.
Important Note: While oxygen is essential for many processes, it can also be dangerous.
* Fire: Oxygen is a key component of fire.
* Oxidative Stress: Too much oxygen can damage cells in the body.
