Question

when iron pipes come in contact with water and oxygen, iron transfers electrons to the oxygen molecules. which statement about the reactants is correct? (1 point)
o oxygen is reduced, and iron is oxidized.
o iron is the oxidizing agent.
o iron is reduced, and oxygen is oxidized.
o oxygen is the reducing agent.

Explanation:

Oxidation is the loss of electrons and reduction is the gain of electrons. Here, iron loses electrons (is oxidized) and oxygen gains electrons (is reduced). The substance that gets oxidized is the reducing agent and the one that gets reduced is the oxidizing agent. So iron is the reducing agent and oxygen is the oxidizing agent.

Answer:

Oxygen is reduced, and iron is oxidized.
