D. Is your answer! Just did it on Apex :)
<span>The enthalpy of the reaction in an aqueous
solution can be determined by taking the difference between the summation of
enthalpies of the products multiplied to their respective stoichiometric
coefficient and the summation of enthalpies of the reactants multiplied to
their respective stoichiometric
coefficient. In this case, the equation is -241(6) + -393.5 (5) -[-119.9] equal to 641.4 kJ </span>
The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.
<h3>What is an atom?</h3>
An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.
The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.
The atomic mass can be given as:
The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:
The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.

Nuclear energy
Nuclear reactors use fission, or the splitting of atoms, to produce energy. Nuclear energy can also be produced through fusion, or joining (fusing) atoms together.
Answer:
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Explanation:
In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
