In science, a chemical reaction is a process that leads to the transformation of one set of chemical substances to another. This typically involves the changing of electron positions in the manipulation of chemical bonds between atoms.

It usually exists as a diatomic molecule.
Its mass is twice as great as the reactants'.
There are two times as many oxygen atoms as reactant atoms.
Its mass increases by two times as a result of the reaction.
In a chemical reaction, matter is not created or destroyed, but is conserved.
Matter can be created and destroyed but does not change forms.
In a chemical reaction, efforts should be made to preserve rare elements without changing them.
In a chemical reaction, the final mass of the products is always greater than the starting mass of the reactants.
