classify the substances by whether they are soluble or insoluble in water. soluble in water insoluble (or very low solubility) in water answer bank nh₃ (ammonia, a polar gas) c₅h₁₂ (pentane, a nonpolar liquid) c₆h₁₂o₆ (fructose, a polar solid) c₂h₆ (ethane, a nonpolar gas) nh₄cl (ammonium chloride, an ionic solid)

Answer

Explanation:

Step1: Recall solubility rule

Like - dissolves - like. Water is a polar solvent. Polar and ionic substances dissolve in polar water. Non - polar substances do not dissolve in water.

Step2: Analyze each substance

  • $NH_3$ is a polar gas. It can form hydrogen bonds with water, so it is soluble.
  • $C_5H_{12}$ is a non - polar liquid. It does not dissolve in water due to non - polar nature.
  • $C_6H_{12}O_6$ is a polar solid. It has many polar groups (hydroxyl groups) that can hydrogen - bond with water, so it is soluble.
  • $C_2H_6$ is a non - polar gas. It is insoluble in water.
  • $NH_4Cl$ is an ionic solid. Ionic compounds generally dissolve in water as water can separate the ions.

Answer:

Soluble in water: $NH_3$ (ammonia, a polar gas), $C_6H_{12}O_6$ (fructose, a polar solid), $NH_4Cl$ (ammonium chloride, an ionic solid) Insoluble (or very low solubility) in water: $C_5H_{12}$ (pentane, a non - polar liquid), $C_2H_6$ (ethane, a non - polar gas)
