AQA A-level Chemistry 3.1.2 Amount of Substance - Unit Workbook and Notes with Answers

(0)
AQA A-level chemistry unit 3.1.2 Amount of Substance - Lesson or Revision workbook with answers This workbook covers a whole unit of work combining detailed information sections with Cornell Style notetaking so the books can be used while you teach and students can add their own notes and ideas down the margin. Colour is used consistently for the different types of sections to make the booklet more dyslexia friendly as I have found that chemistry notes and questions can often be very dense, and somewhat inaccessible for students who have dyslexia. User friendly for students and parents revision too with answers included. This booklet is 46 pages long with answers to past paper questions provided at the back from page 40 onwards. It is provided in word and pdf. Contents Unit conversion The mole and the Avogadro constant Chemical formulae and equations including balancing equations, ionic and half equations Masses, volumes and concentrations in moles and associated calculations Making volumetric solutions Titration Reacting masses, % yield, atom economy Ideal gas equation, pV=nRT Empirical and Molecular Formula Water of crystallisation

(0)
This is a lesson to teach strong and weak acids with an introduction to the meaning of pH. It has a ppt and worksheet in word and pdf format with answers to the worksheet as well. 1) The meaning of strong acid in terms of complete ionisation of acid molecules in water 2) The meaning of weak acid in terms of partial ionisation of acid molecules in water 3) Comparison of the terms concentrated and dilute with strong and weak and an explanation of how a weak acid can still be concentrated and a strong acid could still be dilute. 4) Grid to test understanding of key vocabulary in the ppt file. 5) Meaning of pH in terms of the change in 10x each time you go down a pH unit - does not include logarithms it is described in an accessible way that allows students to calculate changes in concentration as pH unit changes. I write Professor Bunsen resources to teach and test in my own classroom. I hope that I manage to make the new GCSE in chemistry engaging and exciting. Most importantly it could save you and your school time!

Required practicals will replace controlled assessment in the new GCSE. This electrolysis resource is free for a limited time only so please download and make use of it - in both PDF/Word formats with an answer sheet showing the expected results. These record and worksheets are much more than a method. They are designed to track students performance towards achieving their apparatus and skills and provide information to help them understand the background chemistry which is key to understanding an experiment and not just completing it. All the sheets can be bound together in-house into a Required Practicals workbook/log book, or you could hand the sheets out separately. Practical work may be assessed through the terminal examinations - be sure that your students haven't just done the practicals but understand them fully! AQA state: Practical work is at the heart of science – that’s why we have placed it at the heart of each of our GCSE science specifications. By carrying out carefully considered practical work, students will enhance their investigative thinking, improve their mastery of techniques and consolidate their understanding of key scientific concepts. Professor Bunsen resources are tested in school and make the new GCSE in chemistry engaging and exciting.
