Answer: Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

Answer:
3 KOH(aq) + H3PO4(aq) = K3PO4(aq) + 3 H2O
Explanation:
A. the question has a narrow focus
22 + 9 = 31
31 - 17.2 = 13.8
13.8 > 10 so student's guess is wrong
So the 3rd box.
Sodium hydroxide and hydrochloric acid can react with each other to form sodium chloride in the reaction HCl(aq)+NaOH(aq)→H₂O(l)+NaCl(aq).
I hope this helps. Let me know if anything is unclear.
