When molecular or covalent solids dissolve, they break down into individual molecules or discrete units. In the case of molecular solids, these molecules remain intact as they separate from the solid lattice and disperse in the solvent. For covalent network solids, the structure may not dissolve in the traditional sense but can break down into smaller fragments or individual atoms depending on the solvent and conditions. Overall, the dissolution process involves the interaction between the solute molecules and solvent molecules, leading to the solute's dispersion in the solution.

What of the following usually have lower melting points than ionic solids?
Covalent compounds and molecular solids typically have lower melting points than ionic solids. This is because the forces holding covalent and molecular solids together, such as Van der Waals forces and hydrogen bonds, are generally weaker than the strong electrostatic forces present in ionic bonds. Consequently, less energy is required to break these intermolecular interactions in covalent and molecular substances, leading to their lower melting points.
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 are some solids that dissolve and why?
Some examples of solids that dissolve are sugar, salt, and baking soda. Solids dissolve when their molecules break apart and mix with the molecules of a solvent, such as water. This process occurs due to the attractive forces between the solute and solvent molecules.
Are molecular solids malleable?
Molecular solids are generally not malleable. They consist of molecules held together by weak intermolecular forces, such as van der Waals forces or hydrogen bonds, which do not allow for significant deformation without breaking. Instead, when subjected to stress, molecular solids are more likely to shatter or break rather than bend or deform like metals. This brittleness is a characteristic feature of many molecular solids.

If both molecular solids and network solids contain covalent bonds why do network solids have such higher melting points than molecular solids?
Network solids have a three-dimensional structure with strong covalent bonds throughout, leading to a higher melting point compared to molecular solids which have weaker intermolecular forces. In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.
How does hydrogen peroxide dissolve solids?
Hydrogen peroxide can dissolve solids by oxidizing them, breaking down their molecular structure. This chemical reaction causes the solids to break apart into smaller components, which can then be dispersed or dissolved in the solution.

When a molecular solid mixes with water do the covalent bonds within molecules break?
No, when a molecular solid mixes with water, the covalent bonds within the molecules do not break. The solid may dissolve due to intermolecular interactions with water molecules, but the covalent bonds within the molecules remain intact.
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.
Why do molecular solids have lower boiling points than ionic solids?
Molecular solids have lower boiling points than ionic solids because the intermolecular forces between molecules in a molecular solid are weaker than the electrostatic forces between ions in an ionic solid. As a result, less energy is required to break apart the molecular interactions and transition to the gaseous phase in molecular solids compared to ionic solids with stronger ionic bonds.
What are solids that do not dissolve called?
Solids that do not dissolve are called insoluble solids. These solids do not mix with a solvent to form a solution because their particles are too large or their bonds are too strong to break apart.
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.
What are some solids that dissolve and why?
Some examples of solids that dissolve are sugar, salt, and baking soda. Solids dissolve when their molecules break apart and mix with the molecules of a solvent, such as water. This process occurs due to the attractive forces between the solute and solvent molecules.
Solids that dissolve in water?
Salt, sugar, and baking soda are examples of solids that dissolve in water. When these substances are mixed with water, they break down into molecules or ions and disperse throughout the water, forming a homogeneous solution.
