Here is what you have to know from the Chapter 9 in Chemistry Live entitled ” The Mole Concept”. You dont need to know the reasons for them. These notes will include the keys or the tools you need to solve the problems, the problems themselves are simple maths and we might deal with them in another note. In later notes(chapter10 in Chemistry Live) we include the relationship between the mole and volumes of gases. I put in the result here but the explanation/problems come later IA.

Glossary Of Chemistry from skool.ie.

These notes deal with Gas Laws in chemistry. I state what you have to know and dont do any mathematical problems since they are all excellently covered in the text book. These notes are a help for those that already understand the topic. Im not going to go into depth explaining the concepts in these, or any other chemistry notes because then they cease to be notes but rather a rubbish textbook. Needless to say, experiments are not covered here.

Heres what you need to know about from the chapter entitled ” Radioactivity”

Here is notes on the theory, neutralisation, and conjugate pairing of acids.
