<span>When solutes dissolve in water there are two possibilities: 1) either the solute dissociate into ions (which is the case of ionic compounds) and the ions are solvated by the solvent, or 2) in the case of covalent compounds the entire molecule is solvated by the molevules of the solvent (water).

<span>The compound C₃H₆(OH)₂ (propylene glycol) is a covalent compound, so when dissolved in water it will not dissociate but will remain as a molecule, and that molecules is the species solvated by the molecule of water.</span>
Answer: D: a volcano forming a new island in a chain
Explanation:
The greenhouse effect captures the sun's energy and keeps the earth warm.
The hydrogen bond is a comparatively weak interaction between a proton hop and an electronegative atom present in a molecule. The hydrogen bond plays a very important role for the determination of state of a compound like gaseous, liquid or solid. The strength of the hydrogen bond depends on the close distance between the participants i.e. the electronegative atom and proton hop. There remains strong hydrogen bond between the two water molecules which is expressed as O....H. The distance of the hydrogen bond is 1.8A° formed between each proton hops of two neighboring water molecules. The hydrogen bond interaction is shown in the figure.
