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.
In stoichiometry calculations, we assume that reactions run to completion. However, when a chemical reaction is carried out in a closed vessel, the system achieves equilibrium. Equilibrium occurs when there is a constant ratio between the concentration of the reactants and the products.Different reactions have different equilibria.Some may appear to be completely products, however, all reactions have some reactants present.A reaction may look finished when equilibrium is reached, but actually the forward and reverse reactions continue to happen at the same rate.ifferent reactions have different equilibria.
