Ascientist is conducting a descriptive experiment where she is monitoring sea level along coastal towns in california. what is a major benefit of this experiment? the relationship shows cause and effect. it is repeatable. a large amount of data can be collected. results can change over time.

Since the scientist is monitoring the sea levels, she is observing how the sea levels change over time. 

The answer is "Results change over time".

The major benefit of this experiment is either  A. or C.

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
