How does the separation of a mixture containing salt, sand and naphthalene support the law of conservation of matter

Mixtures are not unique to chemistry; we encounter them on a daily basis. The food and drinks ... The mixture that will be separated in this experiment contains three components: Naphthalene ... Dissolving the table salt with water to extract it from the sand by filtration, and. 3. ... support the Law of Conservation of Matter.

Explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
