Question

types of reactions quick check
in a chemical reaction, substance a transfers electrons to substance b. which statement is correct? (1 point)
substance b is reduced and acts as the oxidizing agent.
substance b is oxidized and acts as the reducing agent.
substance a is reduced and acts as the reducing agent.
substance a is oxidized and acts as the oxidizing agent.

Explanation:

In a redox reaction, the substance that donates electrons is oxidized and acts as the reducing agent, while the substance that accepts electrons is reduced and acts as the oxidizing agent. Since substance A transfers electrons to substance B, substance A is oxidized (loses electrons) and substance B is reduced (gains electrons). Substance B, which gains electrons, acts as the oxidizing agent.

Answer:

Substance B is reduced and acts as the oxidizing agent.
