Rank the following substances in order from most soluble in water to least soluble in water: methane, CH4; 2-butanol, C4H9OH; potassium chloride, KCl; and propane, C3H8. Rank from most to least soluble in water. To rank items as equivalent, overlap them.

Arranged in order of most soluble to least soluble in water:

Explanation:

Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.

Non-polar molecules would be dissolved by non-polar solvents.

Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.

answer: c.

explanation:

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
