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.
Do covalent compounds conduct electricity as aqueous solutions?
Most covalent compounds do not conduct electricity as aqueous solutions because they do not dissociate into ions. Covalent compounds typically exist as molecules in solution rather than as ions, which are required for conducting electricity.
Do ionic compounds or covalent compounds have stronger intermolecular forces?
Intermolecular forces are the forces of attraction that exist between molecules in a compound. The stronger the attractions between particles the more difficult it will be to separate them. When substances boil, the particles are completely separated from one another and the attractions between the molecules are completely overcome.
Why are covalently bonded molecular compounds never conductive?
Molecular compounds (these are electrically neutral) would be expected to be poor electrical conductors because the electrons in their covalent bonds are localised and difficult to "move". In any event molecules are separate and possible movement of electrons within the molecule would be difficult to propagate across the intermolecular gap. There are some interesting examples of covalent compounds that do conduct electricity. There are conductive polymers. Some are carbon based but there are others such as polythiazyl a sulfur nitrogen polymer. Strictly these polymers are molecular its just that the molecules are very large, and they are not usually included in the answers to questions like this. See links
Why do ionic bonded molecules disassociate in water?
No. There is no such thing as an "ionic bonded molecule," as molecules, by definition, are helld together by covalent bonds. Ionic compounds are not molecular. Some ionic compounds disassociated in water while others do not.

When molecular or covalent solids dissolve they break down into what?
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.
Which is true of molecular compounds that dissolve in water?
Molecular compounds that dissolve in water are typically polar or can form hydrogen bonds with water molecules. When these compounds dissolve, they often separate into individual molecules rather than ions, as seen with ionic compounds. The solubility of a molecular compound in water is influenced by its molecular structure and the presence of functional groups that interact favorably with water. Examples include sugars and alcohols, which readily dissolve due to their polar characteristics.

Can covalent compounds dissolve in water?
You can NOT dissolve 'covalent BONDS' because a bond is one couple of two electrons which hold their two 'parent' atoms together in one molecule.Try asking the question again with what you want to know, not what you have only 'heard of'.
Is more heat needed to separate molecular compounds than is needed to separate ions?
No, more heat is typically needed to separate ionic compounds than molecular compounds. Ionic compounds have strong electrostatic forces of attraction between ions that require higher energy input to break apart, whereas molecular compounds have weaker intermolecular forces that are easier to overcome.
Why do simple molecular structures have low melting points?
Because although the covalent bonds between the elements are strong, there are only weak forces between the molecules so they have low melting points
How do you separate ionic and covalent compounds in a mixture?
One way to separate ionic and covalent compounds in a mixture is through a process called precipitation. By adding a solvent that selectively dissolves one type of compound while leaving the other insoluble, you can separate the two types of compounds based on their different solubilities. Additionally, techniques such as filtration or chromatography can be used to physically separate the compounds based on their chemical properties.
Which items are related to compounds?
New physical properties are some of the items related to compounds.
