o2 chemistry, why oxygen is written as o2, in this article I m shere a valuable information regarding this.
Hello, reders welcome to another fresh article on “textilesgreen.in”. today i am going to explain about
O2 chemistry, why oxygen is written as o2?
“Why oxygen is written as O2” in case of O2 chemistry because oxygen (O2) consists of two oxygen atoms and it is bound together then it form a molecule. this phenomenon is called oxygen (O2).
Oxygen (O) + oxygen (O) – O2
You can see it is bound together and it make a molecule.
Oxygen is usually found as diatomic gas therefore, we written is as O2.
We know that,
oxygen written is as = O2 and
hydrogen written is as = H2
Oxygen and hydrogen both atom consists two atom of oxygen and two atom of hydrogen and it form a molecule.
You can understand properly with the help of reaction.
2H2 + 2O2 – 2H2O
You can understand how to make water molecule with this reaction.
