What else can I help you with?
What does a high surface tension do to the number of liquid molecules that can stay together?
High surface tension causes more liquid molecules to stay together due to the strong cohesive forces between them. This results in the formation of a compact arrangement at the surface, which resists external forces trying to separate the molecules.
What happens to the solute molecules during the dissolving process?
During the dissolving process, the solute molecules separate and disperse throughout the solvent. The intermolecular forces between the solute and solvent molecules overcome the forces holding the solute molecules together, allowing them to mix and form a homogeneous solution.
What do dipole dipole forces do?
Hold polar molecules together
Carbon tetrachloride CCl4 is nonpolar what forces hold the molecules together?
Van der Waals forces, specifically dispersion forces, hold the nonpolar CCl4 molecules together. These forces are caused by temporary fluctuations in electron distribution within the molecules, creating weak attractions between them.
What is a result of variations in the forces that holds molecules together?
matter
What forces typically separate molecules?
Typically, intermolecular forces such as hydrogen bonding, London dispersion forces, and dipole-dipole interactions are responsible for separating molecules. These forces can vary in strength depending on the nature of the molecules involved.

What is about water molecules that helps explain why the water drops were difficult to split apart but easy to join together?
Water molecules have strong cohesive forces due to hydrogen bonding, which makes it difficult to separate the water drops. When the drops join together, these cohesive forces pull the molecules back together easily due to surface tension, helping the drops recombine effortlessly.
What type of bonding is found in wax?
Wax is typically composed of nonpolar molecules such as hydrocarbons, which are held together by weak van der Waals forces. These forces result from temporary dipoles formed by the movement of electrons in the molecules.
Does branching increase the boiling point of a substance?
No, branching does not typically increase the boiling point of a substance. In fact, branching usually decreases the boiling point because it disrupts the intermolecular forces that hold molecules together, making it easier for them to separate and vaporize.
Why bare covalent molecules typically liquids or gases?
Bare covalent molecules are typically liquids or gases because they have weak intermolecular forces between the molecules. These weak forces are not strong enough to hold the molecules closely together in a solid form, leading to a lower melting point and boiling point. As a result, bare covalent molecules tend to exist as liquids or gases at room temperature.
Carbon tetrachloride CCl4 is nonpolar what forces hold the molecules together?
Van der Waals forces, specifically dispersion forces, hold the nonpolar CCl4 molecules together. These forces are caused by temporary fluctuations in electron distribution within the molecules, creating weak attractions between them.
Why do molecules stay together in outer space?
Molecules stay together in outer space due to intermolecular forces such as Van der Waals forces, hydrogen bonding, and electrostatic attractions. These forces help hold atoms together within molecules and molecules together in solid, liquid, or gaseous states, even in the vacuum of space.

What do the molecules in a liquid hold together?
The molecules in a liquid are held together by intermolecular forces such as hydrogen bonding, van der Waals forces, and dipole-dipole interactions. These forces are weaker than the covalent bonds within the molecules themselves, allowing the molecules to move past each other while still remaining close together.
