A chemical reaction is a process in which one or more substances, known as reactants, are transformed into new substances, known as products, through the breaking and forming of chemical bonds.
Chemical reactions can be classified into different types based on the type of reactants involved, the physical state of the reactants and products, and the energy changes that occur during the reaction.
Oxygen is an essential component in a chemical reaction with both O2 and CO2 released as products. It acts as an oxidizing agent, meaning it helps other substances undergo oxidation reactions and release energy in the form of heat or light.
In a chemical reaction with both O2 and CO2 released as products, carbon dioxide (CO2) is a byproduct of the combustion of hydrocarbon fuels. It is also an important molecule in the Earth's atmosphere, playing a critical role in the carbon cycle and contributing to the greenhouse effect.
No, a chemical reaction with both O2 and CO2 released as products requires an external energy source, such as heat or light, to overcome the activation energy barrier and initiate the reaction. This energy is needed to break the existing bonds in the reactants and form new bonds in the products.
