Is it true that some solids dissolve in water and other solids do not?
it's all about the structure of the particles and the bonds if the chemical bond are mostly ionic they will dissolve to form freely moving ions and some structures of atoms are much stronger like metallic bonds. covalent bonds do not dissolve easily but some covalent bonds break and dissolve in water. It's all about the bond and structures of different elements.
What is taking place at the molecular level during the formation of the solution?
Things are dissolving. Solids break up into ions. for example in a solution of salt water, NaCl is put into water and breaks up into Na+ and Cl-
How do the solvent particles break up from the solute?
When a solute dissolves it breaks apart into its individual particles. The solute and solvent particles mix together and become totally mixed up. That's why a solution is a mixture! As the solute and solvent particles become mixed up, no matter is lost. The overall mass stays the same.
Can a tissue dissolve in water?
You can't dissolve a human, it's atoms are too big and do not break up in water.
What is a mixture in which a substance does not dissolve but does not break into smaller pieces?
a molecule
What do molecular bonds dissolve in?
Molecular bonds don't "dissolve". But, an organic solvent can provide affinity to the molecules you wish to break apart from EACH OTHER...as molecules. Solvents don't break covalent bonds like that. For example, you can dissolve wax in oil, because the wax will DISPERSE within the oil..but the wax molecules will remain wax. If you break the covalent bonds...it would no longer remain wax. Catalysts can break bonds....or some type of replacement reaction of functional groups on a molecule. Okay?

Why do molecular solids usually have lower melting points than ionic solids?
The electrostatic force between the positive ions and the negative ions are very strong, so it requires a large amount if energy to break them. The attractive force between covalent molecular is weak, so less heat energy is required to break it.
What solid is stronger ionic solid or covalent network solids?
Network solids are held together by covalent bonds to each other. They're usually very hard and have high melting points, and are also poor heat and electrical conductors. Think of diamond and graphite. These are covalent network solids. Molecular solids, on the other hand, are molecules held together by weak intermolecular forces (such as dipole-dipole, ion-dipole, or London dispersion forces). These are usually soft with low melting points, and are also poor conductors of heat and electricity. Some examples of molecular solids would be carbon dioxide and benzene. The way I think about it, to help it make more sense to me, is that in covalent network solids, each atom is BONDED to all the other atoms around it. In molecular solids, you have completely separate molecules that are just weakly held together by intermolecular forces, they're not actually bonded to each other.
Are ionic compounds more likely to dissolve in water than covalent compounds?
Often - yes. the reason they break apart is the hydration energy of the ions- many ionic compounds are soluble in water and dissociate into ions, however there are ionic solids such as CaCO3 which are not soluble. The bonds in covalent compunds are often not broken- for example thise in alkanes. However there are covalent compounds which do react with water and dissolve.
When a molecular solid mixes with water do the covalent bonds within molecules break?
No, dissolving does not break covalent bonds. The molecules separate because intermolecular forces such as dipole-dipole attractions are disrupted.
Are network solids malleable?
Covalent network solids are generally not malleable. They have crystal structures that lack obvious glide planes and the covalent bonds are difficult to break and remake. This is a contrast with the metals where many of the crystal structures have glide planes and metallic bonds are relatively easy to break and remake.
What makes solids typpically dissolve faster in hot water?
When solids dissolve in water, their closely packed, crystal lattice breaks. To break this crystal lattice, some amount of energy known as lattice energy must be supplied to the crystal (solid). Hot water molecules have more kinetic energy in them, hence they can impart more energy per collision to the molecules, hence solids dissolve faster in hot water
Why does solid particles doesn't dissolve in water?
Because of the chemical properties of the solids. Some solids have weak chemical bonds which break apart in the presence of water, while others are much stronger and remain connected.
Why is the melting point for ionic compounds higher then the melting point of molecular compounds?
Ionic bonds are stronger than covalent bonds and therefore require more energy to break.
Why does ionic solids have higher melting points compared to molecular solids?
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound
