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 loses electrons (is oxidized) is the reducing agent, and the substance that gains electrons (is reduced) is the oxidizing agent. Since substance A transfers electrons to substance B, substance A is oxidized and acts as the reducing agent, while substance B is reduced and acts as the oxidizing agent.

Answer:

A. Substance B is reduced and acts as the oxidizing agent.
