Dear Year 13
Link to legacy coursework materials - focus on Chemistry A folder
https://drive.google.com/drive/folders/0B-Bvc60KVaFFbDNvN2xSaXdqSTQ?usp=sharing
In the relevant folders I have put a 'USE THESE RESULTS' document or excel file - you will need to as it says use those results to enable you to answer the questions in the paper.
Hope you all have a lovely Easter Break
Miss Chauhan

Fuel Cells research task
For homework this week you will research the use of electrochemical cells as fuel cells.
You need to produce an information leaflet or poster on fuel cells. There will be extra browine points available for creativity!
These are the points on the specification you need to cover:
Storage and fuel cells
(spec point j) application of principles of electrode potentials to modern storage cells (Details of storage cells and required equations will be provided. Relevant electrode potentials and other data will be supplied)
Your work should include a discussion of the benefits of electrochemical cells counteracted by risks from toxicity and fire from Li-based cells.
(spec point k) explanation that a fuel cell uses the energy from the reaction of a fuel with oxygen to create a voltage and the changes that take place at each electrode. (Recall of fuel cells and equations will not be required. Relevant electrode potentials and other data will be supplied).

Year 13 homework
Please have a go at all the tricky questions, using the method we learnt this week. To check your answers use this website:
http://www.webqc.org/balance.php
You may find some of the questions a little impossible! That's okay, we will look at a second method next week.
