Question

which component is transferred between substances in an oxygen - reduction reaction? (1 point)
energy
electrons
protons
oxygen

Explanation:

In an oxygen - reduction reaction (also known as a redox reaction), electrons are transferred between substances. Oxidation involves the loss of electrons, and reduction involves the gain of electrons. Oxygen is often involved in these reactions but is not the transferred component in the general sense of what is transferred between substances in the reaction mechanism. Protons (\(H^{+}\)) can be involved in some redox - related processes (like in acid - base reactions that may accompany redox in biological or electrochemical systems), but the fundamental transfer in the redox reaction itself (the electron - transfer aspect that defines it as a redox reaction) is electrons. Energy is a result or a factor in the reaction (e.g., energy can be released or absorbed), but it is not the component that is transferred in the sense of a particle - like transfer between substances as electrons are.

Answer:

electrons
