Best Answer: Atomic oxygen is just one oxygen atom by itself, written as O. Molecular oxygen is a molecule of two oxygen atoms covalently bonded together, such that both atoms attain the stable octet configuration. It is written as O2. The molar mass simply means the mass of a substance in one mole (in grams). You can refer to your periodic table for the mass number. In this case, oxygen has a mass number of 16.0. Hence, atomic oxygen has a molar mass of 16.0g while molecular oxygen has a molar mass of 16.0*2 = 32.0g.
A reaction's equilibrium constant, Keq, measures the extent to which reactants are converted to products by the reaction. reaction's equilibrium constant, Keq, measures the extent to which reactants are converted to products by the reaction.
Decomposition Reaction Defined. A chemical reaction is a process by which the atoms of one or more substances are rearranged to form different substances. There are many types of chemical reactions. These reactions are often classified by what they form or what happens during the course of the reaction.A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.hese reactions are often classified by what they form or what happens during the course of the reaction.
