BlackZzzverrR [31]

Answer:

B. NH₃ (l) dissolves in water to form a solution

Explanation:

A solution is a uniform or homogenous mixture of two or more substances. The components of a solution are the solute and solvent. The solute is the substance that is being dissolved in another substance. The solvent is the substance which dissolves the solute.

Mixing the given solutes in water results innthe following:

A. Helium being an inert gas does not dissolve in water at all. Therefore, no solution is formed.

B. Liquid ammonia is very solution in water. When mixed with water, it dissolves in water to form aqueous ammonia solution. Aqueous ammonia is an alkaline solution of ammonia dissolved in water.

C. Silicon (iv) oxide, SiO₂, is a crystalline solid whichnis completely insoluble in water. Mixing it with water does not result in the formation of a solution.

D. Pentane, C₅H₁₂, is a liquid hydrocarbon substance which is insoluble in water. It does not mix with water to form a solution, rather it forms two separate immiscible layers of liquids.
