Oxygen can be either a product or a reactant, depending on the situation. As a reactant, it undergoes a chemical reaction with something else to make a product. And it could end up as a product of another chemical reaction. Let's look a bit more closely and see what that means by using examples.
In the case of oxygen as a product, if we immerse a pair of electrodes in water (H2O) and apply a sufficient DC voltage, we'll see hydrogen gas (H2) appear at one electrode (the negative one), and oxygen gas (O2) appear at the other one (the positive one). Here's the equation:
2H2O + energy => 2H2 + O2
In the case of oxygen as a reactant, if we heat carbon monoxide (CO) in air, it will react with the oxygen (O2) in the air to form the product carbon dioxide (CO2). Here's the equation:
2CO + O2 => 2CO2
There are two simple reactions showing oxygen as product and as reactant. Certainly there are many other examples of oxygen as either product or reactant.
That question can be answered as either. It depends what the reaction is that you are performing. Oxygen in the case of producing iron oxide (rust) by the well know process of oxidation, it is a reactant along with iron. But in such a case of electrolysis, the process of splitting water molecules by sending an electrical current through it, oxygen and hydrogen are the products of the decomposition of water. So it really depends whether you are making a compound or decomposing one.
In incomplete combustion of carbon fuels, where there is insufficient oxygen for complete combustion, it will be one of the products. However, even in this situation if the carbon monoxide encounters more oxygen it can still be burned to form carbon dioxide and thus may be a reactant.
Water is the reactant that generates oxygen in photosynthesis through a process known as photolysis, where water molecules are split into oxygen, protons, and electrons in the presence of light.
Water is split into electrons, protons, and oxygen. The oxygen is released as waste.
It can be. Depending on the reaction O2 can be a product or a reactant

What term best describes oxygen in photosynthesis?
Reactant
What gases are the most reactant?
Reactant gases in general include ammonia, methane, nitrous oxide etc. In photosynthesis, however, the reactant gas is carbon dioxide. It produces glucose in plants.Reactant gases in general include ammonia, methane, nitrous oxide etc. In photosynthesis, however, the reactant gas is carbon dioxide. It produces glucose in plants.
What is the gas in the bubbles from photosynthesis?
Photosynthesis produces oxygen.
What are the two things that photosynthesis makes?
Two things that photosynthesis produces is sugar and oxygen.
A reactant in photosynthesis that is a liquid?
Water is a reactant in photosythesis that is a liquid.
What term best describes oxygen in photosynthesis?
Reactant
What element is both a product of photosynthesis and a reactant in respiration?
The element is oxygen. Oxygen is produced during photosynthesis as a byproduct when water is split, and it is then used as a reactant in the process of cellular respiration to release energy from glucose.

What is the gas in the bubbles from photosynthesis?
Photosynthesis produces oxygen.
What substance is both a reactant photosynthesis and a prodcut of cellular respiration?
oxygen
Which gas is a reactant in photosynthesis and which is a product of photosynthesis?
Word equation for photosynthesis: carbon dioxide + water ---in the prescence of sunlight and chlorophyll --> glucose + oxygen Balanced symbol equation: 6CO2 + 6H2O ---> C6H12O6 + 6O2 Therefore the reactant gas is carbon dioxide and the product gas is oxygen.
Carbon dioxide is a product of photosynthesis?
Actually, carbon dioxide is a reactant in photosynthesis. During photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose and oxygen as a byproduct.
What reactant is oxidized during photosynthesis?
Water is the reactant that is oxidized during photosynthesis to release oxygen molecules.
Which process produces oxygen gas in the oxygen cycles?
Photosynthesis
How are cell respiration and photosynthesis connected?
cell respiration consumes oxygen and sugars and produces CO2, photosynthesis consumes CO2 and produces oxygen and sugars
What are the two things that photosynthesis makes?
Two things that photosynthesis produces is sugar and oxygen.
