The explanation of the how the various concentrations of acid will affect the amount of limestone has been given below.
Effects of acid rain on limestone:-
- When an acid combines with a carbonate, it produces carbon dioxide as a gas and forms a salt that is soluble in the carbonate and acid's water.
- There are several gases in the atmosphere that can dissolve in precipitation such as rain and snow.
- Some may produce acids in rain water, such as carbonic acid, sulfuric acid, and nitric acid.
- Because the concentration is modest, the rain is not highly acidic, but it is acidic enough to react with the carbonates that make up limestone.
Thus we discussed the affects of acid rain on limestones above.

Answer:
D) Lead (II) hydroxide is least soluble because the hydroxide ions in water decrease the dissociation of the ions due to the common ion effect.
Explanation:
Answer:
Ka = 6.02x10⁻⁶
Explanation:
The equilibrium that takes place is:
We <u>calculate [H⁺] from the pH</u>:
- [H⁺] =
Keep in mind that [H⁺]=[A⁻].
As for [HA], we know the acid is 0.66% dissociated, in other words:
We <u>calculate [HA]</u>:
Finally we <u>calculate the Ka</u>:
- Ka =
![\frac{[9.12x10^{-4}]*[9.12x10^{-4}]}{[0.138]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B9.12x10%5E%7B-4%7D%5D%2A%5B9.12x10%5E%7B-4%7D%5D%7D%7B%5B0.138%5D%7D)
= 6.02x10⁻⁶
Answer:
Four
Explanation:
AlCl₃(aq) ⟶ Al³⁺(aq) + 3Cl⁻(aq)
One mole of AlCl₃ produces 1 mol of Al³⁺ and 3 mol of Cl⁻.
That's four moles of ions.
