Oxygen is necessary but water vapor is not.
Yes, oxygen is used as a reactant in combustion reactions and is often depleted during the process as it combines with other elements to form combustion products such as carbon dioxide and water vapor. These combustion products contain the oxygen atoms that were part of the original reactant.
A combustion reaction typically involves a reactant containing carbon and produces heat and light as it reacts with oxygen in the air to form carbon dioxide and water vapor.
Heat
Oxygen + organic molecule -------> carbon dioxide + water
Burning of oxygen is a form of combustion, where oxygen reacts with a fuel source to produce heat, light, and often other products like carbon dioxide and water vapor. Decomposition, on the other hand, involves a compound breaking down into simpler substances without the need for oxygen or a fuel source.
Oxygen. Water vapor. Carbon dioxide, if you are a plant...
no it is not
reactants: an element and oxygen products: the oxide of the element
Carbon dioxide (CO2) is a necessary product of a combustion reaction involving a carbon-based fuel source. When the fuel undergoes combustion and reacts with oxygen, CO2 is produced along with heat and sometimes water vapor.
The reactants during burning paper are oxygen and the paper itself, which is mainly composed of cellulose. The products of burning paper are carbon dioxide, water vapor, ash, and some other combustion byproducts.
The word equation for the combustion of coal is: coal + oxygen → carbon dioxide + water vapor.
In the whoosh bottle lab, the reactants are typically a flammable liquid (such as alcohol) and oxygen gas. When ignited, the products are carbon dioxide gas and water vapor, along with a burst of heat and light. A whoosh bottle experiment demonstrates the rapid combustion of the flammable liquid in the presence of oxygen.
