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.

beta decay is the answer
