Answer 1

Answer: C. A metal higher on the activity series list will replace one that is lower.

Explanation: Metal higher on the activity series list will replace one that is lower in a chemical reaction because it has a higher tendency to lose electrons and undergo oxidation compared to the metal it is replacing. This is because metals higher on the activity series have a stronger reducing agent, which means they can more easily donate electrons to other substances and cause reduction. In contrast, metals lower on the activity series have a weaker reducing agent and a lower tendency to lose electrons, making them less reactive in chemical reactions. Therefore, a metal higher on the activity series can displace or replace a metal lower on the activity series by donating electrons to the lower activity metal and causing it to undergo oxidation.
