Listening is a more natural way of learning, when compared to reading. Written
language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through
audio (audio article). You could even learn subconsciously by playing the audio
while you are sleeping! If you are planning to listen a lot, you could try using
a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Silver(I,III) oxide is the inorganic compound with the formula Ag4O4. It is a component of silver oxide-zinc alkaline batteries. It can be prepared by the slow addition of a silver(I) salt to a persulfate solution e.g. AgNO3 to a Na2S2O8 solution.  It adopts an unusual structure, being a mixed-valence compound.  It is a dark brown solid that decomposes with evolution of O2 in water.  It dissolves in concentrated nitric acid to give brown solutions containing the Ag2+ ion.
