They say that non-metals are non -sonorous (does not produce sound).
But wind produces the sound, where air (a mixture of non metals.) under pressure produces a "hooooooooo" sound.

Textbook doesn't tell much about after the reaction as doing it practical. In the Salt and Silver Solution reaction. It precipitates at bottom (or near to the surface w.r.t to a YouTube video of the reaction) in white.
