Respuesta :
Two solutions are mixed and react to produce the solid precipitate AgCl, then the mass remains constant.
What is conservation of mass?
The law of conservation of mass, also known as the principle of mass conservation, asserts that the mass of any system closed to all transfers of matter and energy must remain constant over time.
Since the mass of the system cannot change, and hence quantity cannot be added or removed. In the given reaction when we add two solutions then the mass of the mixture does not changes.
Hence, mass remains constant.
