Remember the order, <n, l, ml, and ms>.
n: energy level
l: subshell
ml: number of orbitals in the subshell.
ms: electron spin.
The first numbers (n) of both the electrons are the same, but the only difference is the second number (l). The first electron has l=2, indicating that the electron is in the "d" subshell. On the other hand, the second electron has l=1, indicating that the electron is in the "p" subshell.
*Remember*
l=0 (s) spherical shape
l=1 (p) peanut shaped
l=2 (d) clover
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
Explanation:
The balanced chemical reaction between copper (II) oxide and carbon monoxide is producing cooper and carbon dioxide:
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
where:
(s) - solid
(g) - gas
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.

The correct answer is that anodization can produce a thin film around the metals, preventing rusting and other kinds of corrosion.
Anodizing refers to an electrolytic passivation procedure used to enhance the thickness of the natural oxide layer on the metal parts surface. The procedure is known as anodizing as the section to be treated produces the anode electrode of an electrolyte cell. The process enhances resistance to corrosion and rusting.
