Answer 1

Answer:

A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. Substances are either chemical elements or compounds.The key difference between 2O and O2 is that 2O refers to two free oxygen atoms, whereas O2 refers to a molecule having two oxygen atoms.

2O and O2 are two terms that often confuse us. Both terms mean that there are two oxygen atoms. But, the difference between 2O and O2 is the state of these oxygen atoms – whether they are free or bound to each other.
