It means that the substance in question will readily react with oxygen.
Almost everything in group 1 of the Periodic Table will react violently with oxygen.
exp. Sodium in powder from will ignite spontaneously when exposed to oxygen.
If something reacts with oxygen that is a description of a chemical property.
In a chemical reaction, the term "reduced" refers to a substance gaining electrons or decreasing its oxidation state. This results in a decrease in the number of positive charges on the atom or molecule. Reduced substances are often involved in redox reactions where they act as electron acceptors.
oxygen
When oxygen reacts with carbon monoxide, it forms carbon dioxide. This reaction releases energy and is often used in combustion processes. Carbon monoxide is oxidized to carbon dioxide in the presence of excess oxygen.
Hydrogen, followed by oxygen. Argon is unreactive.
When sodium reacts with oxygen, it forms sodium oxide (Na2O).
Ozone is a triatomic form of oxygen. It is an allotrope of oxygen.
When magnesium reacts with oxygen, it forms magnesium oxide (MgO).
Iron oxide is formed when iron reacts with oxygen, commonly known as rust.
If something reacts with oxygen that is a description of a chemical property.
oxygen reacts with iron and forms rust Oxygen reacts with iron to form iron oxide.
Magnesium reacts with oxygen to create magnesium oxide. Magnesium(Mg)+Oxygen(O2)--------> magnesium oxide(MgO) 2Mg+O2 ------>2 MgO
Oxygen in the air reacts with heated sphalerite to form zinc oxide and sulfur dioxide.
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.
In a chemical reaction, the term "reduced" refers to a substance gaining electrons or decreasing its oxidation state. This results in a decrease in the number of positive charges on the atom or molecule. Reduced substances are often involved in redox reactions where they act as electron acceptors.
temporary oxygen shortage in cells resulting from strenuous exercise
Potassium reacts violently with oxygen, producing a bright flame and releasing a significant amount of heat.
