AQA A-level / AS Redox reactions, oxidising & reducing agents, working with half equations

AQA A-level / AS Redox reactions, oxidising & reducing agents, working with half equations

AQA A-level / AS Chemistry First powerpoint covers how to determine if a substance is oxidised (oxidized) or reduced in a redox reaction, splitting redox equations into half equations, and oxidising (oxidizing) and reducing agents. Links to the thermite reaction to do as a demo prior to the powerpoint and has an accompanying worksheet. Second powerpoint covers combining redox half equations, links to the first and also has accompanying worksheet.

What are 1 m3 and 1 dm3?

What are 1 m3 and 1 dm3?

AS Chemistry. Visually show how 1 m3 and 1 dm3 are composed of cm3. 1 m3 useful for ideal gas equation; 1 dm3 useful for titrations etc.
