Question

What is happening at the molecular level when a polar molecule like water interacts with a typical sodium ion? The water molecule aligns such that the oxygen interacts with the sodium. The water molecule aligns such that the hydrogens internet with the sodium. The polarity of the water molecule is altered making the oxygen more positively charged. The polarity of the water molecule is altered making the hydrogens more negatively charged. none of the above If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole interaction causes the ions to heat up and vibrate free of the crystal. The ions never overcome their interatomic attraction and therefore are not soluble. none of the above Plastic wrap is made of nonpolar molecules and is able to stick w ell to polar surfaces, such as glass, by way of dipole/induced dipole molecular attractions. How is it that plastic wrap also sticks to itself so well? by way of dipole-dipole molecular attractions by way of dipole-induced dipole molecular attractions Ions are formed as the plastic rubs against itself. by way of induced dipole-induced dipole molecular attractions An adhesive force is best described as attraction between two liquid molecules attraction between a liquid molecule and a solute the force that allows for molecular adhesion the force that holds together the nucleus attraction between two different molecules

Explanation / Answer

41) A: because the Oxygen will have a slight negative charge and the Sodium ion has a 1+ charge. Opposites attract so therefore the Oxygen and Sodium will interact.

42) C

43) D

44) E
