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.

Chemical reactions involve the breakage and formation of chemical bonds, and this has an associated transfer of energy.ndothermic Reactions. Endothermic chemical reactions absorb energy from their surroundings. Usually these reactions cause the surroundings and the reaction mixture to decrease in temperature.
