After this lesson, students should be able to write and balance an equation being given the masses of reactants and products. The starter questions review working out the number of moles of a substance in its mass. The key definitions such as, relative atomic mass, Ar; relative molecular mass, Mr; relative formula mass, Mr; and molar mass, M are revisited. The method in calculating the balancing numbers in a balanced equations from masses of reactants and products is outlined in steps (the masses of reactants and products in grams converted to–> amounts in moles converted to --> simplest whole number ratio) before moving to a workout example. Subsequently, students apply the method to complete questions and check / assess their learning and understanding. Teacher PP supports the workbook; it contains the answers (revealed in steps) to all activities.

Teacher and Student PP that reviews the reaction types and mechanisms of reactions studied over the two years of A Level Chemistry. The resource reviews such key terms as: electrophile, nucleophile, free radical, homolytic bond fission, heterophilic bond fission, carbocation. The following mechanisms are described and explained: free radical substitution nucleophilic substitution electrophilic substitution electrophilic addition nucleophilic addition nucleophilic addition-elimination elimination (haloalkanes with ethanoic hydroxide and alcohols with acid catalyst to form alkenes). The exam questions included give students extensive opportunities to apply their knowledge and assess their progress. Some of the questions contain Stretch and challenge element. Teacher PP is animated and contains all the activities from the Student PP and answers to all activities and exam questions from the Student PP. The resource can be used as a revision aid to prepare for the final exam but can be also used in lessons, over 2Years when students are learning the different mechanisms of reactions.

Some instructions in the workbook and the Summary questions (in assessment part of the booklet) refer to the above book.

Student workbook and teacher PP for OCR A Level Chemistry A Year 2 Chapter 24.3 Stereoisomerism in complex ions. The material covered could be used over two lessons (Lesson 1- cis and trans isomers and Lesson 2- Optical isomers), depending on time available. There is a short review of the conditions for E-Z and cis -trans isomerism in organic molecules and next, cis-trans isomerism is explored in square planar and in octahedral complexes (with six monodentate ligands and in complexes with two bidentate and two monodentate ligands). Optical isomerism is explored in octahedral complexes (with three bidentate ligands and in complexes with two bidentate and two monodentate ligands). The key terms associated with this topic, such as: complex ion, stereoisomers, optical isomers, octahedral shape, square planar, monodentate ligand, bidentate ligand and many more are used extensively. Students are given plenty of application tasks to assess their knowledge. There are many opportunities for student to practise using the wages to represent 3D structures of different isomers. The resources can be used in class, or by students themselves (e.g. if they are not in the lesson). Teacher PP supports Student workbook and contains answers to all questions. The answers are revealed in steps when working through questions. I have just updated this resource to include more recent exam questions. The resource was prepared with the use of A Level Chemistry for OCR A textbooks. Some diagrams and some questions were taken from this book.

This resource can be used for GCSE or for A level Chemistry (as a revision of tests learnt at GCSE). It is a PP intended for a revision of qualitative analysis of positive ions (cations) and negative ions (anions) from GCSE. The first few slides review the tests and the second part of PP contains many exam questions (with answers). The main areas covered in this resource (review and assessment) are: • Making and testing gases; hydrogen, oxygen, chlorine, and carbon dioxide (including balanced equations) • Testing for positive metal – Cu 2+, Fe2+, Fe3+, Al3+, Mg2+ and Ca2+, ions using sodium hydroxide solution (including balanced symbol equations and ionic equations) • Flame tests for metal ions • Testing for anions (sulphates, carbonates, and halides)

The workbook contains step by step activities to develop students confidence at the following: How to decide what type of ions do elements form depending on their position in the periodic table. How to work out the number of protons, neutrons and electrons in atoms and their ions. How to work out the charges on ions, considering the number of sub-atomic particles. How to describe the link between electron structures of ions and Group 0 elements. Teacher PP contains all the activities on the student worksheet and the answers which are, in most cases, revealed in steps. The work sheet also has an extensive starter activity to revisit the knowledge on the periodic table which students need to be familiar with. Some of the questions used here are Chemsheet questions.

This resource is for Combined science and GCSE Chemistry. It is a PP* intended for a revision lesson on Chemical Analysis but not only; the content can be extracted for teaching lessons on Chemical Analysis (e.g., for starters, plenaries, homework or summary of main concepts for notes for students) or for catching up when students miss a lesson. The first few slides contain different types of questions (& answers) -(matching up, application questions, past exam questions and challenge questions) that will allow to assess students’ knowledge up to Grade 9 and above. The slides with the questions could be printed for students. I have also just created a broadsheet * with the questions from the PP. There are 6, A3 pages which can be printed for students. Teachers can select questions suitable for students in their class. The second part of the PP contains slides that review the key concepts for Chemical Analysis in the GCSE Chemistry 2015 specification. Again, the review is suitable for up to Grade 9. The main areas covered in this resource (review and assessment) are: • Purity • Paper Chromatography • Making and testing common gases; hydrogen, oxygen, chlorine, and carbon dioxide (including balanced equations) • Testing for positive metal ions using sodium hydroxide solution (including balanced symbol equations and ionic equations) • Flame tests for metal ions • Testing for anions (sulphates, carbonates, and halides) with an extension for the order of tests if the analysis is being carried out on the same solution) • Instrumental analysis- flame emission spectroscopy
