Answer:
Sinkholes
Sinkholes often form when acidic groundwater or acid rain dissolves limestone, a porous rock present in the soil, creating voids and cavities.

C. The sewage system in a neighborhood
In the reaction we gives the magnesium chloride and released hydrogen gas.
The reaction is carried out by contaning positive and negative charged on elements as follows
Mg + HCl --->MgCl2 + H2
Net reaction gives
Mg+ + 2Cl- + 2H+---> Mg+² + 2Cl- + 2H
Check it Mg(s) and Mg2+ not equal . The donor is element while the acceptor is an ion. The same process is done for H2 (g) and H+.

Here's what I get
Explanation:
SbCl₃ reacts with water to form slightly soluble antimony oxychloride.
SbCl₃(aq) +H₂O(ℓ) ⇌ SbOCl(s) + 2HCl(aq)
Your observation is an example of Le Châtelier's Principle in action,
The SbCl₃(aq) in your lab has enough HCl added to push the position of equilibrium to the left and keep the SbOCl in solution.
If a few drops of the SbCl₃(aq) were added to 300 mL of water, the solution would turn cloudy. The HCl would be so dilute that the position of equilibrium would lie to the right, and a cloudy precipitate of antimony oxychloride would form.
