7F Simple Chemical Reactions

A 19m 18s video on Chemical Reactions from Scientific Eye:

Science in Action – Chemical Reactions – a 19m video; Chemical Reactions (Wan2tlkScience?), a 4m video.

KS3 Bitesize foundation level – Chemical Reactions – a video covering Word Equations, Oxidation & Combustion Reactions, Decomposition Reactions & Helpful & Unhelpful Reactions.

C4 Syllabus Statements

TEXTBOOK REVISION Complete Chemistry for Cambridge IGCSE, chapter 5, pp.66 – 71 & chapter 6, pp.76 – 83

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

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).

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.

Great resources from the Australian International School – videos, powerpoints, worksheets, practicals, animations, flashcards etc.

A good powerpoint that covers most of what you need but misses out calculations for gases and solutions (and you don’t need % composition – slides 13-22):

Writing Formulae & constructing Equations

A superb power-point from Mr Taylor (we thank you):

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.

Metals from Carole Paquette

Here are some key terms for this topic: Key Terms C10

GCSE Bitesize has revision pages (that take you through the topic), a test and an activity – scroll down to ‘metals & their uses’. GCSE s-cool – Metals & the Reactivity Series – revision notes & animations, practise exam questions & a revision summary. For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down. Skoool Chemistry – click on ‘3. Metals, Ores & Rocks’ for excellent lessons on Metals & the Extraction of Metals; also a glossary of key terms. Chemactive worksheets & answers just click on ‘Metals questions’. Great resources from the Australian International School – videos, powerpoints, worksheets, practicals, animations, flashcards etc.

Two more powerpoints:

C10.2 Reactivity Series

Metal-Reactivities-Series

 

Science Bank 3 (Patterns of Reactivity): you just need part 3 (from 8m 50s) covering the reactivity series of metals, displacement & the thermite reaction:

Revision on the Reactivity Series from KS3 Bitesize.

IGCSE Chemistry, a 25m lesson from ChemistryKlipz covers metal reactivity (from 6m 20s to 11m), rusting (to 13m 50s) & displacement rcts (to 18m 30s).

This is a great power-point that also revises C6 Energy changes in chemical reactions:

C7.1 Speed of Reaction

Science Bank (Reactions & Energy Changes): part 2 Reaction Rates (from 4m 40s) & part 3 Catalysts (from 9m 20s):

Five minutes on how to speed up chemical reactions (and get a date) from TED-Ed.

GCSE Bitesize – two videos – Rates of Reaction (3m 18s) or Rates of Reactions (4m 40s) & Bitesize Top 20 Science Demos – Rates of Reaction (5m 51s).
