Chemistry for Cambridge IGCSE schemes of work for term 2. Made from 2020-2022 chemistry 0620 syllabus. The schemes of work are written for every teacher teaching 0620 extended syllabus. For core syllabus, check on other resources.
The schemes of work are professionally designed to include the week, lesson, topic, subtopic to teach, objectives as per the syllabus, teaching activities for each lesson, Teaching aids for each lesson and the remarks session for the teacher to fill if covered successfully or not.

These are a powerpoint presentation on chemistry A level notes on entropy.
The notes have been well written to help students and teachers undertaking chemistry a levels in edexcel IB and cambridge based syllabuses.
What is Entropy
Comparing entropy values
Predicting entropy change
Predicting sign of entropy
Calculating entropy change of a reaction
Spontaneous and non-spontaneous reaction
Calculating the entropy change of the system
Calculating the entropy change of the surroundings
Calculating total entropy change
ROLE OF TEMPERATURE
Why water freeze at -5 but does not at -5
More Entropy changes
Dissolving substances in water
SOLUBILITY OF GROUP 2 SULPHATES AND HYDROXIDES
Lattice energy and born Haber cycles
lattice energy
construct Born–Haber cycles
enthalpy change of atomisation and electron aff inity
eff ect of ionic charge and ionic radius on the numerical magnitude of a lattice energy
■■ interpret and explain qualitatively the trend in the thermal stability of the nitrates and carbonates of Group 2 elements in terms of the charge density of the cation and the polarisability of the large anion.
apply Hess’s law to construct energy cycles to determine enthalpy changes of solution and enthalpy changes of hydration.
■■ interpret and explain qualitatively the variation in solubility of Group 2 sulfates in terms of the relative values of the enthalpy change of hydration and the corresponding lattice energy.

Chemical energetics powerpoint ppt notes for A Level chemistry. These anotes are suitable for teachers teaching both IAL Cambridge and IAL Edexcel.
They are also suitable for learners since they have been created and summarised to suit both teaching and revision

This Powerpoint material is suitable for students and teachers sitting and teaching chemistry in A LEVELS for all syllabuses.
The following are areas covered in this document.
1 explain that catalysts can be homogeneous or heterogeneous
2 describe the mode of action of a heterogeneous catalyst to include adsorption of reactants, bond weakening
and desorption of products, for example:
(a) iron in the Haber process
(b) palladium, platinum and rhodium in the catalytic removal of oxides of nitrogen from the exhaust gases
of car engines
3 describe the mode of action of a homogeneous catalyst by being used in one step and reformed in a later
step, for example:
(a) atmospheric oxides of nitrogen in the oxidation of atmospheric sulfur dioxide
(b) Fe2+ or Fe3+ in the I–/S2O8 2– reaction
4 understand that knowledge of the rate equations for the hydrolysis of
halogenoalkanes can be used to provide evidence for SN1 and SN2 mechanisms for tertiary and primary halogenoalkane hydrolysis
5 be able to use calculations and graphical methods to find the activation energy for a reaction from experimental data
The Arrhenius equation will be given if needed.
6 understand the use of a solid (heterogeneous) catalyst for industrial reactions, inthe gas phase, in terms of providing a surface for the reaction

This is a powerpoint display notes meant for Cambridge, Edexcel and IB chemistry teachers and students.
The se are notes that I use to teach in my class. They ahve been well prepared using the three core books.
The notes include;
Brønsted– Lowry theory of acids and bases
diff erences in behaviour between strong and weak acids and bases and the pH values of their aqueous solutions in terms of the extent of dissociation.
AMPHOTERIC AND AMPHIPROTIC
Conjugate acids and conjugate bases
NITRIC ACID AS A BASE
terms pH, pKa and Kw and use them in calculations
[H+(aq)] and pH values for strong and weak acids and strong bases
choice of suitable indicators for acid–base titrations
changes in pH during acid–base titrations and explain these changes in terms of the strengths of the acids and bases
calculate Ksp from concentrations and vice versa
common ion eff ect
term partition coeff icient
partition coeff icient for a system in which the solute is in the same molecular state in the two solvents.
PH CURVES AND INDICATORS
How a buffer solution works
Making a Buffer solution
How to make a buffer
Calculating the pH of a buffer solution
Uses of Buffers
