Add 500 ml of 1 M HCl solution to 500 ml of solution with 4.25g AgNO3 dissolved, a precipitate and filtrate are obtained. a) Calculate the mass of the precipitate obtained.
b) Calculate the molar concentration of the substance remaining in the filtered water. Assume that the volume of filtered water obtained does not change significantly.

The answer should be vaporization 

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Ido not understand. 

Idon't know hope someone you
