r stands for "the rest of a molecule". Since there are about 20 different amino acids, it could be any one of the 20.
it is inorganic
When studying Chemistry or almost any science, it is important to know how to read Chemical formulas. The formula Cl2 stands for Chloride.
The periodic table of elements lists Cl as chloride. Cl2 is Chlorine like the chlorine used in bleach and in similar compounds. It can also be used in detergents and dish soap.

it is inorganic
Cl2 is chlorine. Chlorine exists as a diatomic molecule.
At STP, Cl2 gas has a density of 0.0032g/mL. (Wikipedia article, "Chlorine") 0.30g Cl2 x (1mL Cl2/0.0032g) = 93.75mL Cl2
Simply, the reactants are the original substances that are present at the beginning of a reaction. For example, in this reaction: 2Na + Cl2--> 2NaCl, the reactants are the Na and Cl.
An example is:C2H4 + Cl2 = C2H4Cl2

MgBr2 + Cl2 yields MgCl2 + Br2 is an example of an anionic single replacement chemical reaction.

Cl2 (properly written the 2 would be a subscript - but that's tough to do here) represents a diatomic molecule of chlorine. At standard conditions, this is the form pure chlorine takes.
