Answer:
the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers.
Explanation:

Answer: 0.3
Explanation:
We know that
Ka = [H+] * [A-] / [HA]
And the acid is 15 % dissociated means that
[A-] / [HA] *100 = 15%
So
[A-] / [HA] = 0.15
Then we know that [H+] = [A-] = 2 molar
Replacing we have
Ka = 2 molar * 0.15 = 0.3
The equation of the reaction is;
Ca(OH)2(aq) + 2HCl(aq) ------> CaCl2(aq) + 2H2O(l)
<h3>What is neutralization?</h3>
The term neutralization has to do with the process in which an acid reacts with a base to form salt and water only. A neutralization reaction is known by the fact that water is obtained by the reaction of hydrogen and hydroxide ions.
The equation of the reaction is;
Ca(OH)2(aq) + 2HCl(aq) ------> CaCl2(aq) + 2H2O(l)

Answer: A porous black solid, consisting of an amorphous form of carbon, is obtained as a residue when wood, bone, or other organic matter is heated in the absence of air.
Explanation: Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln
