I think the correct answer from the choices listed above is the third option. The magnetic quantum number of an electron (m) designates the orientation in space of the orbital (electron cloud). <span>This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell. </span>
The density of the metal sphere is 2 times the density of the liquid as proved.
<h3>Net upward force acting on the metal sphere</h3>
The net upward force acting on the sphere as it is dropped into the liquid is calculated as follows;
F = σVg - ρVg
ma = σVg - ρVg
where;
- ρ is density of the liquid
- σ is the density of the metal
- a is acceleration of the metal
σV(a) = σVg - ρVg
σ(a) = σg - ρg
σ(g/2) = σg - ρg
g(σ/2) = g(σ - ρ)
σ/2 = σ - ρ
σ/2 - σ = - ρ
-σ/2 = - ρ
σ = 2ρ --- proved
Thus, the density of the metal sphere is 2 times the density of the liquid as proved.

Answer:
Rusting!
Explanation:
Rusting is a chemical reaction because it is the process of oxidation of a metal.
