LEL away on Thursday

Dear 12eCh and 12dCh,

I am away on Thursday - I'm interviewing so will be around but not able to be in the lesson. In my absence could you please investigate the development of the model of benzene and produce some succinct notes. You need to be able to:

1. Describe the kekule structure of benzene
2. Explain the evidence for and against the kekule structure of benzene
3. Describe the orbital model of of benzene
4. Explain the evidence for the orbital model of benzene

I will go over it in class by picking on you and expecting you to know something about it!

Have a nice day without me.

Yours

Ms Elias

cover for period 2 today

You need to answer some of the exam questions that I have posted on the blog (below) – there are 504 minutes worth in total (if you ignore any overlaps). Some questions have come out a little weird and it is impossible to read the scale (so don’t do those) and you’ve not learnt anything about fermentation – so ignore these questions too!

Have fun without me. I’ve booked the library computers for your use (not the ones on the stage) so you could ask Mrs Cook to boot the other 6^th formers out.

In total this is 504 minutes worth of questions!

Cover work for 12e on 12th May

Apologies I will not be able to see you today.

Please read pages 146-147 of the text book and answer the questions on page 147.  There is graph paper on the door of W9 which you will need to do this.

Please also complete the worksheet on rates and collision theory (also stuck on the door).

Best wishes,

PAG 5.1 for LEL Y12 Chemists

Good afternoon,

12dCh and I discovered, this morning, that PAG5.1 does not work. The mixture does not separate, even following some intervention with other solvents and by trying to "salt it out". This means that we will not be doing PAG 5.1 on Wednesday or Friday and will instead be starting PAG5.2.

If you read this message before the lesson please don't complete your homework and instead we will assess the risk of the chemicals at the start of the lesson, as the DNA.

Yours
Ms Elias
