Made this during my GCSEs: https://docs.google.com/file/d/0B1A3...VKYmJOZVk/edit.
These aren't covered in the document:
To test for hydrogen, put a lighted splint in hydrogen gas and there should be a squeaky pop if hydrogen is present.
For oxygen, it should relight a glowing splint.
For carbon dioxide, it will make lime water cloudy if it is present.
PS the link to the Word document may not stay there forever, so you might want to download the file.
