Product:
* Combustion: When fuels like wood, oil, or natural gas burn, they react with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). This is a common example where CO2 is a product.
* Cellular Respiration: Living organisms, including humans, use oxygen to break down sugars and produce energy. This process releases carbon dioxide as a waste product.
Reactant:
* Photosynthesis: Plants use carbon dioxide from the atmosphere, along with water and sunlight, to produce their own food (sugars) and oxygen. Here, CO2 is a key reactant.
* Carbonation: When CO2 is dissolved in water, it forms carbonic acid (H2CO3). This is what makes fizzy drinks carbonated.
In short:
* Carbon dioxide is a product of combustion and respiration.
* Carbon dioxide is a reactant in photosynthesis and carbonation.
