Entropy - calculating total entropy

(1)
A revision resource with questions on calculating entropy of the system, surroundings, total entropy and entropy of solution for dissolving ionic salts. Answers are included within the editable worksheet which allows students to mark their work and monitor their progress. The questions get more difficult as each section progresses.

Redox Ecell game

I used this with my year 13 class and they loved it. An excellent revision resource. Students have to answer a question on Ecell if they land on a star. Question cards on Ecell are included in this resource.
Amount of substance (1 of 2)

Amount of substance (1 of 2)

(1)
An A-Level Chemistry resource on calculating Amount of substance (Moles). The worksheet is differentiated with each section increasing in difficulty. Answers are included with each section so that students can check their progress. This is the first half of this resource, the 2nd half is also available on this website with 2 more pages on atom economy, empirical formulae, percentage yield etc. The complete set has 16 sections in total. If you like this resource there are others of a similar format on calculating entropy, pH, Kc, Kp, Grignard reagents, inorganic formulae, Ecell, pV = nRT etc. These sheets conrain examples of every type of exam questions atudents may face.
Transition metal reactions

Transition metal reactions

(0)
PowerPoints going over the reactions of Transition metals, deprotonation, ligand exchange. relevant for A-level Chemistry. Also includes another Power Point on the colours of the Transition metal precipitates.
Thermal decomposition of carbonates and nitrates (group 1 and 2)

Thermal decomposition of carbonates and nitrates (group 1 and 2)

(0)
Eight resources on the thermal decomposition of the group 1 and 2 nitrates and carbonates. The first resource is a differentiated worksheet with the questions designed around the style of AQA, Edexcel and OCR exam papers and test students on every aspect of the topic including the reactions, observations, trends, theory of charge density/polarisation and finishes with a few questions on how we measure it experimentally. I looked at exam papers from all three exam boards when designing this resource so that it provides comprehensive coverage for my students. Answers are included. There is also a resource which goes through the qualitative observations associated with thermal decomposition of the carbonates and nitrates (what’s observed e.g limewater goes cloudy, brown gas of Nitrogen dioxide etc). I have also included a spider diagram of the reactions/observations and Power Points which explain the science behind it. There is then a hexagon activity and a challenge grid, both designed at stretching & challenging the students.
Electrode potentials and electrochemical cells

Electrode potentials and electrochemical cells

This is a differentiated A-level chemistry revision resource covering the different types of Ecell questions. There are 8 sections, each one increasing in difficulty. The resource is editable and the markscheme is provided. Could be used in a revision lesson at the end of the topic. There is also useful tips on how to calculate Ecell and writing of cell diagrams. There is one of every type of Ecell question that students could be tested on in an exam. Takes about 2 hours to complete. I also have several other resources like this one in my shop on moles, pV=nRT, redox titrations, entropy, Equilibrium Kc & Kp, pH calculations and also buffer calculations. Each one covers all the different types of calculations they need to revise for the exams.
