Year 12 into 13 Summer Homework
Here is the holiday work for the summer break. You should print them off and complete them. If you need any specific guidance then scan/photograph your attempt and email to Dave or Mimi for feedback. Later on in the break I'll post some marking guidance for self assessment. You need to bring in all tasks to go in your folders in your first week of 2018/2019. These will help you prepare for the 2018 AS papers we will be doing before the end of September.
Enjoy!
Enjoy!

Friday 16th March - 12B and 12F Dave's groups (not 12C Thurs group!!)
12B - read and make notes on using Bond Enthalpies to find enthalpy changes in reactions. Use your text book or www.chemguide.co.uk - we will look at some examples of this in Wed lesson next week.
12B and 12F - answer the questions attached on Enthalpy Changes - I need to see them completed by the end of next week (we will peer assess on Fri 23rd)

12F Mon 5th Feb
Revision for Mock on Wednesday – Revision videos on below and you also have the practice paper (and mark scheme) to be working through. Please remember to pick up the recent test from Jen – Jen will make a copy of the mark scheme available on Google Classroom.
12C Thursday 18th - Use the videos and tasks below to revise for the Feb exam
3rd Jan 2018 - Redox Chemistry
Revision summary including how to determine oxidation states, disproportionation reactions and balancing redox equations. Watch, summarize and practice using questions in text book or past papers.

2nd Jan 2018 - Using the Ideal Gas Equation to find the molar mass of a gas
The video shows how to use pV=nRT to find the molar mass of a gas, a common problem at GCE level. It's short and uses SI units. Lots of the US videos online use a variety of non SI units - AVOID THESE!!
Go through the video then go back to you text book to check you can do the examples in topic 5 |

1st Jan 2018 Electronegativity
Go through the help sheet below (from www.knockhardy.co.uk) and use it to check your understanding of electronegativity. Use highlighters (or highlighter tool if using the pdf) to mark ideas as red, amber, or green, depending on your level of understanding. Then go through the sheet again to improve amber/red areas. Check understanding with questions on sheet and from text book.

31st December - NYE Shapes of Molecules Quiz - who says revision isn't fun, fun, fun?
Follow the link below;
http://www.knockhardy.org.uk/sci_htm_files/mcshape.HTM
30th December - Summary of Bonding and Structure (Topic 2)
This summary goes through all the basics of bonding and structure from GCSE and Year 12 and introduces other ideas such as shapes of molecules and intermolecular forces, which are then used throughout the course. Got through it in small chunks, making bullet point notes / mind maps etc. Then check your understanding by trying out the questions at the end of topic 2 in your text book (link to answers further down this page).
|
|
29th Dec - Summary of Group 2 Chemistry (Topic 4)
Exactly what it says on the tin - a powerpoint summary of topic 4 - useful to remind you of all the bits you've forgotten. Got through it in small chunks, making bullet point notes / mind maps etc. Then check your understanding by trying out the questions at the end of topic 4 in your text book (link to answers further down this page)

Reacting Mass Calculations
Watch the video on the right to remind yourself how to calculate reacting masses, using amounts in moles. Practice the technique by changing the masses.
|
|
More revision for Feb mock.
Watch the video on the right and make sure you can process data from an acid-base titration to find an unknown concentration.
Practice several times by changing the data. Mastery of this technique will give you a better chance of having strategies to deal with unstructured problems. |

What happens when the halide ions reduce sulfuric acid?
We saw in class that concentrated phosphoric acid will form HX from KX, but the video below shows that some of the halide ions (bromide and iodide) can act as reducing agents when the react with concentrated sulfuric acid. The video on the right highlights the changes that occur, showing the changes in oxidation state and the equations that occur. You may need to go through this two or three times.

12F (and 12C) - watch this summary of key observations when halides react with conc.sulfuric acid
12F and 12C Dave's groups - a few more topic 5 questions to have a look at for next week - 12F hand in Mon 18th, 12C Thur 14th

Thursday 23rd November 12 C Chem Cover Work
Red text book - Questions on pV=nRT Section 5.1.42 of book
Red text book - Questions on molar gas volumes Sections 5.2.4 and 5.2.5 of book Red text book - Questions on titration calculations Section 5.3.4 of book These can be self assessed. The answers can be found via the link below; This link takes you to the Pearson site with the answers to the questions in the Pearson Text book (Curtis, Murgatroyd and Scott)....No excuses now...you should be doing them all and self assessing as part of revision http://www.pearsonschoolsandfecolleges.co.uk/Secondary/Science/16Biology/Edexcel-A-level-Science-2015/FreeResources/FreeResources.aspx Don't worry about the bit in the link that says biology...that's because the Pearson bio text book answers are on the same site! Homework Challenge - Download, print and complete the two AS exam questions on the right These will be collected next week for teacher assessment |

Thur 16th November 12C Chem -
Here are the answers to the marked homework on reacting masses handed back today. Use them to 'purple pen' your work to identify your errors.
Common errors included; incorrectly calculating relative formula masses, esp. for hydrated salts; failure to check ratio and use accordingly, BIDMAS errors using calculator. There were very few 'method' errors - it was unforced slips like the ones described above. If you have lost the question sheet then see further down this page.

Cover Work (Flip Learning) for Dave's group - Wednesday 8th November
Make notes on the Ideal Gas Equation; pV=nRT. Use your text book (or www.chemguide.co.uk) to find out what each symbol stands for and what units they are measured in. Make sure you can rearrange the equation and find out how the equation can be used to find a molecular mass. We will do some problems based on this (and empirical formulae) next Monday.
Concentration Homework - for both groups - due in w/c 23/10

The document below will help you tackle the change from GCSE ideas and concepts to the higher demands of A level. You should print it off, read it carefully and start to complete the tasks. These tasks help make sure the key skills from GCSE are embedded early on in the A level course. We will expect to see your answers in the week commencing 18/9/2017. Good luck!
