Activity 1A (Textbook) – Chemistry Form 5 Chapter 1 (Redox Equilibrium)


Activity 1A:
Carry out a discussion to answer the following questions in a brainstorming activity.
1. The reaction between copper(II) oxide, CuO and carbon, C is an example of a redox reaction.
(a) Write a balanced chemical equation for the reaction that takes place.

(b) State the names of the reactions that take place for:
(i) Copper(II) oxide, CuO .
(ii) Carbon, C.

(c) Identify:
(i) Oxidised substance.
(iii) Oxidising agent.
(ii) Reduced substance.
(iv) Reducing agent.

Record the outcome of your group’s discussion in your notebook.

Answer:
(a) 2CuO + C → 2Cu + CO2

(b)(i) Reduction reaction
(ii) Oxidation reaction

(c)(i) Carbon
(ii) Copper(II) oxide
(iii) Copper(II) oxide
(iv) Carbon
