Chem 5th Form Assignment

5th Form Assignment/project

In groups of three (3) prepare a power point presentation on one of the options below. Your presentation should include but is not limited to: - A cover page- include teacher’s name, students’ names, and date - A title page - A table of content - A brief introduction which lists the objectives of the presentation and outline the contributions made by each member. - A list of references - An assessment activity (quiz, worksheet, etc.)

Presentations will be assessed for:

Content (10 marks) The information must be accurate, relevant and appropriate

Creativity (10 marks) The presentation should be aesthetically appealing; ensure that there is contrast between text and background. Select an appropriate font style, font size, and colour such that your presentation is visible from the back of your classroom. You should also include special effects, sound, and animation where appropriate. Also ensure that there is adequate interaction (quiz, questions, etc) between the presenter(s) and the target audience.

Organization (10 marks) The presentation should be arranged in a logical and sequential manner. It should last between twenty-five (25) and thirty (30) minutes.

Option 1 Define the terms electrolysis, cathode, anode, cation, anion Define the terms electrolyte, strong electrolyte, weak electrolyte, nonelectrolyte, conductor, and insulator. Describe investigations leading to the classification of substances as conductors, insulators, or electrolytes. Classify electrolytes as strong and weak based on their conductivity. Distinguish between metallic and electrolytic conduction.

Option 2 Identify ions present in electrolytes Draw simple diagrams to represent electrolytic cells Predict the electrode to which an ion will drift Describe with equations the reactions taking place at electrodes Identify the factors affecting the formation of products during electrolysis Predict chemical reactions making use of the electrochemical series

Option 3 Identify concentration as a factor which affects the formation of products during electrolysis. Discuss the electrolysis of : (i) Concentrated copper (II) chloride solution (ii) Concentrated zinc sulphide solution (iii)Concentrated iron (III) bromide (iv)Concentrated sodium chloride using graphite electrode Identify type of electrode as a factor which affects the formation of products during electrolysis. Discuss the electrolysis of aqueous copper(II) sulphate(VI) using graphite electrodes Discuss the electrolysis of aqueous copper(II) sulphate(VI) using copper electrodes

Option 4 Discuss the electrolysis of water using graphite electrodes Investigate the electrolysis of copper (II) sulphate (VI) solution using graphite and copper electrodes. Explain the formula Q = It Define the faraday constant

Perform calculations involving the faraday constant Give examples of calculations involving masses and volumes of substances liberated during electrolysis.

Option 5

Identify the factors which affect the rate of chemical reactions Explain how these factors affect the rate of reaction

Option 9 Express results obtained from experiments on rates of reaction in the form of tables and graphs where appropriate. Draw graphs to represent data obtained from experiments involving rates of reaction Extrapolate and make predictions from graph Analyze and interpret graphs and or data Compare and contrast enzymes (biological catalysts) with inorganic catalysts.

Option 10 Define energetics Distinguish between exothermic and endothermic reactions in terms of energy content of products and reactants Draw detailed energy profile diagrams for endothermic and exothermic reactions Define activation energy Draw general energy profile diagrams for endothermic and exothermic reactions Draw and interpret energy profile diagrams for catalyzed and uncatalyzed reactions Perform calculations involving heat change

Note: 1. Include equations wherever they are appropriate. 2. If necessary, seek clarification and assistance from your teacher.
