When a double replacement reaction produced one compound that is soluble and one compounds that is insoluble, a. only the solution of dissolved ion resultsb. only a solid is formedc. the soluble compound exists as dissolved ions in a solution while insoluble compound forms as a precipitated. none

c. the soluble compound exists as dissolved ions in a solution while insoluble compound forms as a precipitated.

Explanation:

Let's consider an example of a double displacement reaction that produces a soluble compound and an insoluble one.

BaCl₂(aq) + Na₂SO₄(aq) ⇒ NaCl(aq) + BaSO₄(s)↓

NaCl is a soluble compound so it is dissolved in the solution. It is also an electrolyte so it ionizes in water according to the following equation:

NaCl(aq) ⇒ Na⁺(aq) + Cl⁻(aq)

BaSO₄ is insoluble so it remains as a precipitate.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
