Are the water molecules more strongly hydrated to the monovalent cation of the trivalent cation?
Yes, water molecules are generally more strongly hydrated to trivalent cations compared to monovalent cations. This is because trivalent cations, having a higher charge and smaller ionic radius, create a stronger electrostatic field that attracts water molecules more effectively. The increased charge density of trivalent cations leads to a higher degree of hydration, resulting in more water molecules being associated with them.

What happen when hydrated borax is heated strongly?
On heating, borax first loses water molecules and swells up.On further heating it turns into a transparent liquid, which solidifies into glass like material known as borax bead. Na2B4O7.10H2O -----heat------>Na2B4O7------heat------>2NaBO2+B2O3 Sodium Boric metaborate anhydride
Why a lithium atom holds its outer electrons more strongly?
Neither of these metals hold onto their outer electron (singular, as they are alkali metals) very strongly. Relatively speaking though, lithium holds onto its outer-most electron more strongly than Sodium does.

What is observed when Fe2SO4 and FeSO4.7H2O are heated strongly?
When FeSO4·7H2O is heated strongly, it loses its water molecules and forms anhydrous FeSO4. The color changes from blue to white or pale green due to the removal of water molecules, and the compound becomes anhydrous iron(II) sulfate (FeSO4).
When a liquid is heated strongly its density?
decreases as the molecules move further apart due to increased kinetic energy and reduced intermolecular forces.
Why hydrated salts are not wet?
The water molecules become a part of the crysal structure. 5 water molecules atttach to Cu SO4 to make the hydrated crystal. The reason it is not wet is because the 5 water molecules are more strongly attracted to the CuSO4 than to anything else in its environment. So those 5 water molecules do not wipe off on to your hand, or a towel.

What factors cause a cation to be strongly hydrated?
In a similar method to lattice energy, size and charge are the key factors. The more charged the cation is, the closer it will pull other molecules to it=stronger. The smaller the cation, the less levels of electron shielding get in the way, letting other molecules be pulled closer=stronger. The stronger the forces, the stronger the attraction to water=hydration.

Do water molecules attract nonpolar molecules such as oil?
Yes, but they attract polar molecules more strongly."Hydrophobic" molecules is a misnomer. The nonpolar molecules in question are attracted to water molecules (usually more strongly than they're attracted to each other, even), but they get "shoved out of the way" by polar "hydrophilic" molecules which are even more strongly attracted to water molecules.
Molecules in what state are strongly attracted to each other but can change positions?
The molecules in a liquid state are strongly attracted to each other but still have enough kinetic energy to move around and change positions. This allows liquids to flow and take the shape of their container.
What physical change happens to atoms and molecules in a solution that is strongly heated in a flame?
When a solution is strongly heated in a flame, the atoms and molecules gain kinetic energy, causing them to move faster and collide more frequently. This can lead to increased chemical reactions, vaporization of the solution, and potentially decomposition of the molecules into smaller fragments or different chemical species.
Do polar and nonpolar molecules interact?
In general, polar molecules interact more strongly with other polar molecules (due to dipole-dipole interactions) and nonpolar molecules interact more with other nonpolar molecules (via London dispersion forces). However, there can be exceptions depending on the specific molecules involved and the conditions of the interaction.
Is O2 hydrophobic?
Yes, O2 (oxygen gas) is not considered hydrophobic. It is a nonpolar molecule and does not interact strongly with water molecules, making it more soluble in water compared to hydrophobic molecules.
Why don't water molecules and oxygen molecules attract each other?
Water molecules are polar due to the unequal sharing of electrons between oxygen and hydrogen atoms, while oxygen molecules are nonpolar. As a result, water molecules are attracted to each other through hydrogen bonding, but do not interact strongly with nonpolar oxygen molecules.
