Read each question carefully and provide your answers in the space provided. For balancing redox equations, show all your steps clearly.
1. Which of the following statements is true regarding an oxidation-reduction (redox) reaction?
Oxidation is the gain of electrons, and reduction is the loss of electrons.
Both oxidation and reduction involve the loss of electrons.
Oxidation is the loss of electrons, and reduction is the gain of electrons.
Neither oxidation nor reduction involves the transfer of electrons.
2. In the reaction 2Na + Cl₂ → 2NaCl, what is oxidized?
Na
Cl₂
NaCl
None of the above
3. The species that causes oxidation by accepting electrons is called the agent.
4. In a redox reaction, the oxidation number of an element that is oxidized will .
5. Rusting of iron is an example of a reaction.
6. An oxidizing agent is itself reduced in a redox reaction.
True
False
7. The sum of the oxidation numbers of all atoms in a polyatomic ion equals the charge of the ion.
True
False
8. Assign oxidation numbers to each atom in the following compounds:
a) H₂SO₄
b) K₂Cr₂O₇
9. Balance the following redox reaction using the half-reaction method in acidic solution:
MnO₄⁻(aq) + Fe²⁺(aq) → Mn²⁺(aq) + Fe³⁺(aq)
10. Observe the image below. This image shows a rusty chain. Explain how the process of rusting is an example of a redox reaction, identifying what is oxidized and what is reduced.
