Edexcel 2015 Topic 15 A Transition metals, main focus on this is ligands and shapes, also includes electron configuration of transition metals. Specification points included on lesson titled pages. Hyperlinked for easy navigation.
Topic 15B - colours and precipitates coming shortly
This resource is designed for the Pearson Edexcel 2015 A level Chemistry course. The purpose of this document is to help to standardise the observations of the core practicals that are available from Edexcel. In the event that more than one teacher are assessing practical experiments, it is good practice for the centre/ school to have standardised and agreed the criteria in awarding the competencies. This document provides a completed framework for that purpose and is able to be edited and updated. It is recommended that colleagues meet to discuss this when required. It could be checked yearly and discussed in departmental meetings.
Edexcel do not offer a document such as this but do mention it in their CPAC guidance. They have a sample one on their website but do not have guidance for all of the core practicals.
A resource to help teach topic 15B of the Edexcel A-level Chemistry curriculum.
Any activities will mostly include answers but on an occassion, the teacher should know how to answer it.
The PowerPoint provides examples in how to calculate Kc and Kp.
More detail is now assessed in relation to the reaction quotient in describing how equilibrium is re-established, the PowerPoint provides examples in how to account for such changes.
This is tailored for the Edexcel specification Topic 11.
Specification : Topic 11
1. be able to deduce an expression for Kp, for homogeneous and heterogeneous
systems, in terms of equilibrium partial pressures in atm
2. be able to calculate a value, with units where appropriate, for the equilibrium
constant (Kc and Kp) for homogeneous and heterogeneous reactions, from
experimental data
3. know the effect of changing temperature on the equilibrium constant (Kc and Kp),
for both exothermic and endothermic reactions
4. understand that the effect of temperature on the position of equilibrium is
explained using a change in the value of the equilibrium constant
5. understand that the value of the equilibrium constant is not affected by changes
in concentration or pressure or by the addition of a catalyst
The PowerPoint outlines information for:
History of the Atom
Structure of the atom
How to write formulae
How to write balanced equations
Isotopes and calculating relative atomic mass
Separating techniques: distillation, fractional distillation, re-crystallisation, chromatography.
The fundamentals of Chemistry are important, if pupils cannot write formulae, they will struggle if choosing to study at A-level.
Some worksheets have been included for some activities described.
The PowerPoint makes reference to pages in the CGP CGSE Chemistry Exam Practice book. This is just a reference only and can be deleted.
The mind map has a synthesis approach where students can test their knowledge on reaction routes and conditions. Answers are included on the other side.
A revision map is also available for Topic 6.
The recrystallisation resources are to help help students understand the process of recrystallisation. This is a purification step that is required in most A level Chemistry courses.
Card sort activity:
students identify the steps required when doing recrystallisation.
It could be laminated and then the boxes cut to produce the card pieces.
Students then pair them with the right image and in the right sequence.
Notes and exam question:
This is to help students see the correct sequence of images from the card sort activity and to provide useful information to explain each step.
The files are word and can be edited as desired for further adaptation.
A flow diagram for students to test themselves of the reagents needed for Organic Chemistry Topic 6. There are answers on one side and a means to test themselves on the other.
All of the reactions for benzene, one side provides answers the other the student can use to test themselves.
Another is available for further organic Topic 17 and AS topic 6
This PowerPoint presentation gives details in how to:
1) Write formulae and ionic equations
2) What the mole is and why it is the number that it is.
3) Reacting mass calculations with examples/ animations
4) Empirical formulae, simple, converting to molecular formula and water of crystallisation.
5) Molar gas volumes
6) Ideal gas equation
7) Concentration and explaining differences in mol dm^-3 and g dm^-3
This is designed for the Edexcel new specification in Chemistry. However the concepts are transferrable.
The PowerPoint is hyperlinked accordingly for easy navigation.
This PowerPoint presentation is hyperlinked to various topics that include electrolysis of molten and aqueous solutions.
In addition, there is a 'story board' worksheet for students to follow an animation and annotate to the various stages.
It is best suited for GCSE candidates of those doing double and higher award.
This presentation is tailored towards the iGCSE specification but can be applied to other exam boards.
This topic is big, this PowerPoint focuses on 6D and 6E only.
Core practicals explanations are included.
For your information:
Sn1 and Sn2 are not explained in this PowerPoint. (this may be incorporated in future for the linear course)
Updated PowerPoint to cover Edexcel Specification (see below)
Includes theory, some exercises and hyperlinks to navigate to various points. These slides don't make a lesson by themselves although in some instances have been used to take the entire lesson, the teacher will still need to produce and have worksheets to hand to practise.
A-level teaching requires significant more input from the teacher, the teacher's knowledge of reagents and conditions needs to be good to identify some exercise answers which includes from Topic 6.
The PowerPoint includes mechanisms of reactions including the triiodoform reaction. This goes beyond the specification - to explain what is occurring.
Please do look for my further organic revision mind map which tests students on reagents and conditions/ includes answers. I have also created a revision mind map and PowerPoint for Topic 6.
Topic 17A: Chirality
Topic 17B: Carbonyl compounds
Topic 17C: Carboxylic acids
Topic 15 Transition Metals Precipitation reactions worksheet
This worksheet allows students to test themselves of the colours, precipitates and formulae produced from the reactions of Cu2+, Co2+, Fe2+, Fe3+, Cr3+ with ammonia/ NaOH, excess, HCl and reduction and oxidation of Cr. Answer sheet also available.
Showing mechanisms of electrophilic substitution with benzene and various electrophiles.
Includes comments on the structure of benzene and evidence to support the delocalised ring system model.
This is tailored for the new edexcel specification.
Revision aid that informs students what words can or cannot be used - could be useful for A-level to recap the basic concepts.
Could be used as a framework to help students answer questions on structure types and refer to the sheet for support.
Revision mind map for students to use to revise various parts of the book. Some material can be completed on the sheet while other questions direct the pupil to research the answers.
