1 Bridging the Gap Welcome to Dereham Sixth Form College. Before you start your Chemistry course in September you need to have completed this booklet and all associated tasks. It has been wri en for you, as students, to help give you some prac ce of key skills that you will be using over the next two years. There will be some GCSE content that you need to be confident with and some A Level material that will be part of the founda on we will build on in lessons. Deadline This is to be completed over the summer and handed in during your FIRST chemistry lesson in September. Name: High School: Induc on Teacher:

2 Course Material The following textbooks are used throughout the course and will form the basis for your examina ons, you will need to purchase your own copy of this book: Places you can purchase this book: Oxford University Press h ps://goo.gl/sj2bbd Amazon UK h ps://goo.gl/pglmdg WHSmith h ps://goo.gl/7k8vjs ISBN: Price Range: (including second hand prices) It is highly recommended that you have a look at the following links as they contain informa on that is relevant to the chemistry course or are useful places to find addi onal material that will help develop your understanding in the subject. OCR Chemistry A A Level Specifica on: h ps://goo.gl/mco5dj OCR Prac cal Skills Handbook: h ps://goo.gl/sbxutm OCR Maths Skills Handbook for GCE Chemistry: h ps://goo.gl/52ggpz OCR Periodic Table of Elements: h ps://goo.gl/xxu1ja Royal Society of Chemistry; Learn Chemistry: h p:// chemistry/ Royal Society of Chemistry Resources: h p:// chemistry/resource Chemicool Interac ve Periodic Table: Chemguide Doc Brown h ps://goo.gl/fhfjm8 Edmodo is an online educa on network that enables students and teachers to communicate and interact with digital resources. Throughout the Chemistry course you will find that lots of resources, lessons and messages are passed through Edmodo. You will need to create an account (if you don t already have one) and sign up to the A Level Chemistry group. The Group code will be given to you in lesson. PLEASE BE AWARE THAT THE GROUP CODE IS ONLY ACTIVE FOR A COUPLE OF WEEKS SO PLEASE SIGN UP QUICKLY Group Code: Part of your bridging work is to complete the ques ons by using this link: h ps://goo.gl/2itjyd This is assessed online; instruc ons are provided when you log in. This is not a compulsory assignment but there is a prize for the two people with the highest scores. For your login details and further informa on please Mr Russell: srussell.northgate@dsfc.org.uk 2

K (s) + Cl 2(g) KCl (s) 2. Zn (s) + HF (aq) ZnF 2(s) + H 2(g) 3. H 2 O (l) + Na (s) 4. C 6 H 12 O 6(s) + O 2(g) CO 2(g) + H 2 O (g) 5. H 3 PO 4(aq) + Ca(OH) 2(aq) Ca 3 (PO 4 ) 2(s) + H 2 O (l) Determine the chemical formulae of the following ionic substances (SOME of the ions have been given to you, others you should know from GCSE) Posi ve Ions Nega ve Ions 1. Silver nitrate: 2. Ammonium Hydroxide: 3. Calcium Chloride: 4. Iron (II) sulphide: Ag + NO 3 NH 4 + OH Fe 2+ (iron II) SO 4 2 Fe 3+ (iron III) CO Sodium Nitride: Cu 2+ NO 3 6. Copper Sulphate: 7. Potassium Carbonate: 8. Iron (III) Nitrate: 9. Aluminium Oxide: 3

4 A mole is a chemical unit based on Avogadro s Number. One mole of atoms contains 6 x atoms, no ma er what element it is. This number is used in chemistry because if you could count out this many carbon atoms, the total mass of carbon you would have is 12 g, which is the same as its atomic mass. One mole of water weighs 18g because the atomic mass of oxygen is 16, the atomic mass of hydrogen is 1, water has the formula H 2 O = 18. Calculate the number of moles or mass of the materials below; Moles: 1. 22g CO 2 : 2. 75g CaCO 3 : 3. 16g CuSO 4 : g Mg(NO 3 ) 2 : g Fe(OH) 3 : g NiCl 2 (PC 18 H 15 ) 2 : Mass mol LiAlH 4 : mol C 60 : mol NaCl: 4. 3 mol (NH 4 ) 3 PO 4 : mol CaCO 3 : mol NaBH 4 : How may individual atoms are in the following materials: mol of Na: mol Li: 5. 4x10 6 mol N 2 : mol of O 2 : mol K: mol H 2 SO 4 : Describe the similari es and differences between a base and an alkali: Give an example of the following chemical reac ons, with the products, as a word and balanced symbol equa on and iden fy what type of reac on they are: Inorganic Acid + Metal Oxide Inorganic Acid + Metal Hydroxide Inorganic Acid + Metal Carbonate Type of reac on: Ionic Equa on: 4

5 For the experiment you did in your introductory lesson, write a method and include a labelled diagram of the equipment you used. Draw and complete a results table for the tra on you completed. Show your workings for your averages. 5

6 Concentra on is measured in mol dm 3 (moles per decimetre cubed / moles per litre). From this you can calculate the amount of a substance used and do mole calcula ons for a solu on. Calculate the concentra on of the solu on you made using the two triangles below: Write a balanced symbol equa on for the reac on that you carried out What is the ra o of sodium hydroxide to hydrochloric acid? Calculate the concentra on of the hydrochloric acid solu on using your tra on results. Assuming that the stock solu on your acid came from had a total volume of 5L, what mass of anhydrous hydrogen chloride would be needed to make a stock at this concentra on? 6

11 The next part of your bridging work is to complete an independent research task on one of the following topics: 1. Chemistry of animal communica on 2. Chemistry and journalism 3. Chemistry of pharmaceu cal developments 4. Chemistry in environmental management 5. Chemistry and nutri on 6. The art of war and Chemistry 7. Chemistry of foods and flavourings 8. Chemical and biological signalling 9. Chemistry and DNA 10. Ultra high density polymerisa on 11. Chemistry of replacing fossil fuels 12. Chemical applica on of flora and fauna 13. Spli ng the atom 14. Air sensi ve Chemistry 15. Cataly c Chemistry 16. Chemistry of waste management 17. Criminal Chemistry 18. Bioac ve chemicals For this task you will be required to research in detail one of these topics. You will need to create your own specific ques on as these topics are very broad. The idea is to select a topic that will interest you and be something you can fully engage with. There will need to be a good level of detail with full and accurate referencing in the Harvard Style (see back page). A comprehensive report with a good level of spelling, punctua on and gramma cal structure will be expected. Accurate and appropriate scien fic terminology is to be used throughout. 19. Non Newtonian Chemistry 20. Chemistry and Popular Culture 21. Chemistry in Electronics 22. Chemistry and Body Image 23. Detec ng Chemicals 11
