Answer is: <span>3 particles would one formula unit of CaCl</span>₂<span> produce when dissolved in solution.
Chemical reaction of calcium chloride dissolving in water:
CaCl</span>₂(aq) → Ca²⁺(aq) + 2Cl⁻(aq).
<span>There are one calcium cation and two chlorine anions in solution from one formula unit of calcium chloride.</span>
An extensive property depends on the amount of matter; an intensive property depends on the type of matter. Mass and volume are extensive properties. Color and hardness are intensive properties.
Answer:
Hydrogen sulfide is used primarily to produce sulfuric acid and sulfur. It is also used to create a variety of inorganic sulfides used to create pesticides, leather, dyes, and pharmaceuticals. Hydrogen sulfide is used to produce heavy water for nuclear power plants (like CANDU reactors specifically).

Explanation:
We have to calculate value.
It is known that at the equivalence point concentration of acid is equal to the concentration of anion formed.
Hence, [HA] =
Now, relation between and pH is as follows.
pH =
Putting the values into the above formula as follows.
pH =
4.23 = (as [HA] = )
= 4.23 (as log (1) = 0)
or, = 4
Thus, we can conclude that of given weak acid is 4.
