Chemical calculations knowledge organiser

(0)
A knowledge organiser on the AQA GCSE topic Chemical calculations. Includes information on the scientific terms: RAM, RFM, conservation of mass, mole, avagadro constant, excess & limiting reagents, titrations , formulae trianagles for all the calculations etc. Also contains more depth on the steps required in a titration, diagrams of flasks used and indicators etc. Also includes information about volume of gases, atom economy and percentage yield. Is everything the students need to know on one page before attempting the calculations. Can be expanded onto an A3 page. Relevant for the new 2018 exams.
A-Level Chemistry knowledge organisers

A-Level Chemistry knowledge organisers

20 Resources
A bundle of 20 knowledge organisers I have made for the new 2015 A-Level Chemistry syllabuses. The knowledge organisers are on the following topics: atomic structure and the periodic table, acid base equilibria (pH), Ecell, thermodynamics (Entropy), Equilibrium, organic chemistry (hydrocarbons, crude oil, fuels, organic synthesis, polymers, proteins, DNA, amino acids), transition metals, periodic table, bonding and infra red spectra. The knowledge organisers have complete coverage of all the knowledge students need to know before they go on to tackle exam questions.
Entropy Knowledge organiser
polarity24polarity24

Entropy Knowledge organiser

(1)
An Alevel Chemistry knowledge organiser on entropy. Includes information on entropy, feasability, entropy of the system, surroundings, total entropy, Gibbs free energy, temperature at which a reaction becomes feasible etc. Comprehensively covers the whole of the entropy syllabus on one page.
Gibbs Free energy calculations
polarity24polarity24

Gibbs Free energy calculations

(0)
Some A-Level Chemistry resources on the thermodynamics topic of Gibbs free energy. The first resource contains 6 sections of calculations with each section increasing in difficulty. This resource is differentiated and takes about an hour to complete. Is excellent revision on Gibbs free energy calculations and nicely prepares students for the exam with relevant exam standard calculations including a graph. Answers are included. Also included are Entropy worksheets (with answers) on calculating Gibbs and how it is related to the equilibrium constant.
Equilibrium knowledge organiser
polarity24polarity24

Equilibrium knowledge organiser

(0)
An A-Level Chemistry knowledge organiser on equilibrium. Covers knowledge on Le Chatelier’s principle, examples of how equilibrium is affected, equations for Kc and Kp, partial pressure, mole fraction etc. Also information on the Haber process and the Haber compromise, dynamic equilibrium etc. A comprehensive organiser that covers everything that students need to know on equilibrium in year 12 and 13.
