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
Equations and Reacting Masses Homework - Dave's Groups - due in 4th (12F) or 5th(12C) Oct
There is no need to do the questions that are crossed out!
Making the change from GCSE to A level
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!
