Show the energy of Oxidation of two mole pyruvic acid.
DerKrebs [107]

Answer:

Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.

Atoms with high ionization energy allow their electrons to easily be taken
nlexa [21]

Answer:

FALSE

Explanation:

Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.
