What is Question 13?
Question 13 is a structured question that consists of three parts: (a), (b), and (c). The question is as follows:
(a) Define oxidation and reduction in terms of electron transfer.
(b) Identify the oxidizing agent and the reducing agent in the following redox reaction:
(c) Write the half-equations for the oxidation and reduction processes that occur in the reaction in (b).
How to Answer Question 13?
To answer question 13, you need to follow these steps:
For part (a), you need to recall the definition of oxidation and reduction in terms of electron transfer. Oxidation is the loss of electrons, while reduction is the gain of electrons. You can use the mnemonic OIL RIG to remember this. You can write your answer as follows:
Oxidation is the loss of electrons.
Reduction is the gain of electrons.
For part (b), you need to identify the oxidizing agent and the reducing agent in the given redox reaction. The oxidizing agent is the substance that causes oxidation by accepting electrons, while the reducing agent is the substance that causes reduction by donating electrons. You can use another mnemonic LEO GER to remember this. You can write your answer as follows:
The oxidizing agent is Cl2.
The reducing agent is Fe.
For part (c), you need to write the half-equations for the oxidation and reduction processes that occur in the reaction. A half-equation shows how electrons are transferred in a redox reaction. To write a half-equation, you need to balance the atoms, charges, and electrons. You can write your answer as follows:
Oxidation: Fe → Fe + e
Reduction: Cl2 + 2e → 2Cl
Conclusion
In conclusion, question 13 in the Chemistry Form 5 Module Nilam is a question that tests your understanding of redox reactions. To answer this question, you need to recall the definitions of oxidation and reduction, identify the oxidizing agent and the reducing agent, and write the half-equations for the oxidation and reduction processes. By following these steps, you can ace this question and score full marks. 0efd9a6b88
