<h3>Hey Mate Here Is Your Answer:-</h3>
<h3>C- Diffusion</h3>
Reason:- The Mechanism of Diffusion In the case of food coloring in water, the water is the solvent while the food coloring is the solute. Once they've mixed, they make a solution. Diffusion takes time, though how much time depends on the kinetic energy of the molecules randomly bouncing among each other.

Answer:
120mph
Explanation:
Google
divide the speed value by 1.467
or
176 times 60 second in a minute times 60 minutes in an hour
than divide by 5280 the amount of feet in a mile
Redox reactions are those <u>chemical reactions that involve the transfer of electrons between reactants</u>, altering the <em>oxidation state</em> of their elements.
In this type of reactions an element releases electrons that another element accepts, so there is a net transfer of charge.
When balancing redox reactions, not only must the chemical elements in the reactants and products be equalized (by the <em>law of conservation of the mass</em>), but also the charged that is transferred in the process must be balanced, since <u>the electrons that are lost in oxidation are the same as those that are gained in reduction (</u><em>law of conservation of charge:</em> <em>there is no destruction or net creation of electric charge</em>).
From the calculations performed, the Kb of the reaction is 9.9 * 10^-10
<h3>What is Kb?</h3>
The term Kb refers to the base dissociation constant of a solution. We have the following information from the question;
pH of the solution = 8.60
concentration of p-toluidine = 0.016-M
Recall that pOH = 14 - pH
pOH = 14 - 8.60 = 5.4
[OH] = Antilog (-5.4) = 3.98 * 10^-6 M
We have to set up the ICE table;
CH3C6H4NH2(aq) + H2O(l) ⇄ CH3C6H4NH3^+(aq) + OH^-(aq)
I 0.016 0 0
C -x +x +x
E 0.016 - x 3.98 * 10^-6 3.98 * 10^-6
Hence;
Kb = [3.98 * 10^-6]^2/[0.016 - 3.98 * 10^-6]
Kb = 9.9 * 10^-10

In chemistry for an chemical equation to be complete it has to be balanced using appropriate coefficients and state symbols such similar atoms are equal in both sides of the equation. The reaction between hydrogen sulphide and oxygen gas yields sulphur iv oxide and water as indicated by equation.
2H2S (g) + 3O2 (g) = 2SO2(g)+ 2H2O(l).
therefore the correct answer is 2,3,2,2
