C4 Stoichiometry (Combined Science)

Leave a reply

Here are some key terms for this topic: Key Terms C4

IGCSE Chemistry: Topic 4 Stoichiometry, a series of 9 lessons from Sal Sciab.

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 – Writing Formulae & Balancing Equations (includes ‘the Mole’ but not molar calculations) – revision notes & animations, practise exam questions & a revision summary. Worksheets from Mr Guch that cover Naming Compounds; and here are some more. And here’s some more on Balancing Equations. Also Chemactive worksheets & answers just click on Reactions questions.

For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down.

The law of conservation of mass – Todd Ramsey – a 4m 30s TED-Ed lesson.

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.

IGCSE Chemistry: Topic 4 Stoichiometry, a series of 9 lessons from Sal Sciab.

IGCSE Chemistry: Basic Calculations, a 15m lesson from ChemistryKlipz (some of which we don’t need for the exam).

A good powerpoint that covers most of what you need but misses out calculations for gases and solutions:

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):

How to use the formula triangles – from GCSE Bitesize.

Practice here – some mole calculation worksheets and Stoichiometry from Mister Guch and some chemical calculations from Doc Brown.

Quantitative chemistry from GCSE Bitesize – just revise the bits you need though (use the syllabus statements to decide). A Quantitative Chemistry quiz – for teams or individuals.

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.
