1. What is the process of losing electrons in a chemical reaction called?
Reduction
Oxidation
Neutralization
Hydrolysis
2. In the reaction 2Na + Cl2 → 2NaCl, which element is oxidized?
Sodium (Na)
Chlorine (Cl)
Both Na and Cl
Neither Na nor Cl
1. An oxidizing agent is a substance that causes another substance to be oxidized.
True
False
2. Rusting of iron is an example of a reduction reaction.
True
False
1. Oxidation is the of electrons, while reduction is the gain of electrons.
2. A substance that is oxidized is called a agent.
3. The oxidation number of an uncombined element is always .
1. Define oxidation in terms of both electron transfer and change in oxidation number.
2. Explain why redox reactions always occur in pairs.
Observe the image below, which shows a rusted metal object.
3. Based on your understanding of oxidation, describe what is happening to the metal in the image.
