Here are some key terms for this topic: Key Terms C4
IGCSE Chemistry: Topic 4 , a series of 9 lessons from Sal Sciab. Stoichiometry
IGCSE Chemistry: Basic Calculations , a 15m lesson from ChemistryKlipz (some of which we don’t need for the exam).
2 videos on Stoichiometry which probably go into too much detail but are very good – Hank Green from Crash Course Chemistry talks very fast & Salman Khan does not.
A good powerpoint that covers most of what you need but misses out calculations for gases and solutions:
A superb power-point from Mr Taylor (we thank you):
Reactions & Formulas from Stephen Taylor
Balancing chemical equations (from the Khan Academy):
You can practise balancing chemical reactions here – and it’s fun (honestly). Or you could play . Chemical Compound Hangman
GCSE s-cool – (includes ‘the Mole’ but not molar calculations) – Writing Formulae & Balancing Equations revision notes & animations, practise exam questions & a revision summary. Worksheets from Mr Guch that cover ; and Naming Compounds are some more. And here’s some more on here . Also Balancing Equations just click on Reactions questions. Chemactive worksheets & answers
For Doc Brown’s Chemistry
quizzes, word-fills, crosswords and study notes go and just scroll down. here
– Todd Ramsey – a 4m 30s TED-Ed lesson. The law of conservation of mass
What is the RAM? – The Virtual School (3m 53s):
IGCSE Chemistry: Atoms, Elements & Compounds , a 19m lesson from ChemistryKlipz that covers the structure of atoms, relative atomic masses and isotopes, formulae of elements and compounds, and relative formula masses.
Stoichiometry & The Mole from Stephen Taylor
IGCSE Chemistry: Calculations involving Moles , a 16m lesson from ChemistryKlipz.
What is a mole? – The Virtual School (3m 49s):
Molar Volumes of Gases – The Virtual School (3m 23s):
Practice here – some and mole calculation worksheets from Mister Guch Stoichiometry and some from Doc Brown. chemical calculations
from GCSE Bitesize – just revise the bits you need though (use the syllabus statements to decide). A Quantitative chemistry – for teams or individuals. Quantitative Chemistry quiz
A Mole Music Video by Peter Weatherall (1m 48s).
‘Calculations involving the use of limiting reactants may be set’:
What would happen if you had a mole of moles? . The fantastic What if? site answers this question. The answer is rather unpleasant.
