Do 1. Human activity causes changes to the groundwater and surface water in a watershed. Which change to groundwater or surface water is classified as a
chemical change?

Dsolubility let me know if you have any other questions for chemistry

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The answer is not c

The correct answer would be b) volume versus temperature, because they are also directly proportional.
