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
=======
Difluorophosphoric acid is an inorganic compound with the formula HPO2F2.  It is a colorless liquid. The acid has limited applications, in part because it is thermally and hydrolytically unstable.It is prepared by hydrolysis of phosphorus oxyfluoride:

POF3  +  H2O  →  HPO2F2  +  HFFurther hydrolysis gives monofluorophosphoric acid:

HPO2F2  +  H2O  →  H2PO3F  +  HFComplete hydrolysis gives phosphoric acid:

H2PO3F  +  H2O  →  H3PO4  +  HFThe salts of difluorophosphoric acid are known as difluorophosphates.
