Answer:
D. 
Explanation:
Hello!
In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:
Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:


Unlike the other reactions whereas no change in the oxidation states is evidenced.

<span>When an electron, which is negatively charged, moves towards an electronegative atom, the electronegative atom pulls in the electron. This causes the electronegative atom to be reduced. This entire process also releases energy.</span>
The sample with the largest number of oxygen atoms will be calcium perchlorate.
<h3>Number of atoms in a compound</h3>
Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.
- The chemical formula for carbon dioxide is
. Thus, it has 2 atoms of oxygen. - The chemical formula for potassium chlorate is
. Thus, it has 3 oxygen atoms. - The chemical formula for calcium perchlorate is
. Thus, it has 8 atoms of oxygen. - The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.
Therefore, the compound with the largest number of oxygen atoms is calcium perchlorate.
