ERA Year 13s

Dear students,

Your assessment on rates will be next week.  It will be a 90 minute paper and will include questions on the practical work we have done this topic, as well as the points covered in the powerpoint I shared in the holidays.

13C - please bring your PAG work to the lesson on Wednesday.  I will look through your PAG folders while you are doing the paper.

Please come and see me if you have any questions about how to prepare for this assesment.

Miss Rayment

ERA Homework for next week

Using the student sheet, on a separate piece of lined paper with the title PAG 10.1 (teacher demo) and the date please write:

1. The method for this reaction, but with suitable equipment included in every step of the method
2. A table of results - make sure you include the quantities of each reagent in this table
3.  Answers to the analysis questions and the extension questions (good exam prep).

Following this, please got to www.bit.ly/PAG101 and make a results table in the google spreadsheet with your name on it.

It should automatically calculate the concentration of iodine and the rate.  This calculation will be different as the concentrations you are given in the PAG are different.

Rates revision ppt

Dear all,

Please use the link below to access a revision powerpoint on the rates topic.

https://drive.google.com/drive/folders/0B970e2T7WXvPd3pRNzJ5Zm1TcFE?usp=sharing

It goes through each spec point and gives some ideas for your revision.  It is a starting point only - you should be developing your own revision plans and strategies alongside this.

Best wishes,
ERA

Year 13 - Missing homework

Dear all,

I was meant to set you a homework but forgot :( This was to keep you busy over the holidays and get us ahead a little. If you see this message then the homework is to:

1.  Research and produce notes on the following reactions of carbonyls - the mechanism for nucleophilic addition reactions of aldehydes and ketones with NaBH₄ and HCN to form alcohols and hydroxynitriles respectively               

•   For NaBH₄, the nucleophile can be considered as being the hydride ion, H^–, with subsequent protonation of the organic intermediate from H₂O.
• v For HCN, initial nucleophilic attack is from CN^– ions; subsequent protonation stage can be shown using H₂O or H⁺.

1. 2      Then to complete a pack of questions on carbonyls. These you can collect from my classroom and are in the deep tray labelled 13CCh.

When I remember how to put files on here I’ll post a copy up. 

It is due first lesson in w/c 7th November.

Dear 13D Chemists

Holiday Homework

Please bring a completed version of your method and a print out of your graph on Tuesday 1st November - you will also have a test on rates period 3.

I have uploaded your results into a file linked below:

https://drive.google.com/drive/folders/0B-Bvc60KVaFFczNBd0JDQTJMblk?usp=sharing

You will need to write a detailed method for the practical that you carried out in the lesson:
See PAG instructions below:

Records

As evidence for the Practical Endorsement, you should have recorded evidence of all your measurements and any relevant observations in a suitable format. You should also include a record of the equipment that you used, and any adaptations you made to your method while you completed the activity. You should save your spreadsheet with processed data, which will provide a record of the volumes of solutions you used for each experiment. If you keep hardcopy records, you may want to include a printout of your spreadsheet data there too. All work should be clearly dated.

You will also have a test on Tuesday 1st November - the test will be on everything that we have done on rates.

Please email me if you can't access the spreadsheet

Hope you have a restful half-term

Many thanks

Miss Chauhan

Extra difficult questions to help you prepare for the unknown

Dear all,

I found an extra resouce on the web.  They might be good practice for the tricky application/unstructured questions in F324 and F325.  Please look at the "stretch and challenge" folder inside the link below. NB you will have to download the whole folder as it is in zip format atm.

Best,
ERA

Revision stuff

Dear all,

As requested I have uploaded the redox equation practice Q and my answers.  Also you are apparently missing the last set of answers to the analysis past paper questions - these are also in the folder below.

Hope your revision is going well!  You have been very luck to have such miserable weather, I hate revising when it's sunny outside.

Miss Rayment


Revision stuff that you requested

Revision seminar - Redox

You are all invited to a revision seminar on Redox next Wednesday (18th may).  It will run from 4 until 5.30 pm in J37.

We will remind you during the week.  It should be really useful.  :-)

ERA

Dates for next two weeks

I just wanted to confirm the mocks and coursework sessions running over the next two weeks - I think I may have got muddled up on Friday, sorry.

Next week:
F324 retake, open to all, after school on Thursday (5th May)
Final quantitative task, open to all, after school on Friday (6th May)

Week after next:
13e F325 mock, Thursday P5 - this will run over I'm afraid.  You are welcome to come at the beginning of lunch to get started early. (12th May)
13b F325 mock, Friday P1&2 (13th May)

Bonus opportunity: Spectroscopy in a suitcase, two sessions (P1&2 and P3&4), open to all.  It involves some visitors from Oxford Uni with £10,000s of spectroscopy equipment.  They will present you with an unknown chemical and some data, you will collect some data and then work out what it is.  Great revision for F324.

Resources from today

Dear 13b,

Well done for getting through such a mammoth lesson today.  I have added the powerpoints to the resources folder below if you want to go through the slides again.

13e - you might also want to have a look, especially those that missed the lesson on Thursday.

Revision questions - they are working!

I've just learnt that the revision questions look like they might not work - I think this just a problem with the preview though.  If you download the whole thing it does work.  Please try and download it :-)

F325 revision resources

Dear Year 13

I have put together a set of revision questions to help you with your F325 revision this holiday (mark scheme and examiners report included).  It's really important that you are frequently revising and testing your knowledge of the course.  You will need to divide your time between preparing for your final evaluative paper (see below) revising F325 and F324.

Remember - knowing all of the content of the course will get you to around a grade C (in both papers).  Higher grades come from being able to apply your knowledge and answer questions in new contexts.

Next term we should aim to practice the higher grade skills (as soon as we finish transition metals).  To do this you will have to already have learnt the course (that we have covered so far).

13b - I have also included a powerpoint on the colours of select transition metals in solution and in their hydroxide precipitates.  Please work through the powerpoint and learn these colours.

Easter resources

Enjoy your holiday!

Revision for progress test on Thermodynamics

As promised, you will sit a progress test on everything we covered last term (Born-Haber cycles and Entropy) next week.

I have added some AQA past paper questions to your resources folder.  These will be really helpful for you to check you have understood these topics and can apply your knowledge.

OCR past paper questions are also in the resources folder.  You have already completed these but it is worth visiting them again to check you can still answer them (accurately) and know where you've gone wrong in the past.  These should also be used to check you know how the questions are likely to be set and what they tend to look for in the mark scheme.

See you next week,
ERA

Work for this week

Apologies for not being in today.  I hope to be back in school ASAP.

Please spend your time today marking your entropy past paper questions and going back over the Born Haber cycle questions.  All the resources you need are in the resources folder which you can get to by the link below.

The Born Haber practice questions are especially relevant to your coursework on Thursday.  Make sure you have fully understood all of these questions and can answer them accurately.  I have marked your first attempts at these questions and will return them to you as soon as I can.

ERA Re-take

Dear Year 13,

Please find a retake paper and mark scheme, from my side of the course, through the link below.  If you did not reach your target on my side of the course, you should do some extra revision, complete this paper under exam conditions and then mark it.

NB.  It includes a question on titration curves and enthalpy of neutralisation

Please hand your marked papers in, to me, I will check your marking and make a note of your second attempt.

This paper will also be extremely good preparation for your next piece of evaluative coursework.  I strongly recommend that you all use it to help you revise.
