Explain why oil does not dissolve in water.?
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
What is the intermolecular force that exists between Na and water?
The intermolecular force that exists between Na and water is primarily ionic bonding. When Na is placed in water, the water molecules surround the Na ions and form hydration shells due to the attraction between the positively charged Na ions and the negatively charged oxygen atoms in water molecules.
What type of intermolecular force is found in water molecules in ice?
Hydrogen bonding is the intermolecular force found in water molecules in ice. This occurs when the partially positive hydrogen atom of one water molecule is attracted to the partially negative oxygen atom of another water molecule.
Dissolving a solid in water usually an endothermic change?
Dissolving a solid in water is typically an exothermic process because energy is released when the solute particles mix with the solvent particles. The energy released usually comes from the formation of new intermolecular bonds between the solute and solvent molecules.
Is dissolving suger in hot water a chemical or physical?
Dissolving sugar in hot water is a chemical change.
What is responsible for holding water molecules together in the liquid state?
The main intermolecular force holding water molecules together in hydrogen bonding. Also, there are diplole-dipole interactions and London dispersion forces. But hydrogen bonds are the major force keeping water in the liquid state.
What is the strongest intermolecular force between two molecules of water in ice?
The strongest intermolecular force between two molecules of water in ice is hydrogen bonding.
Is the attraction between sodium chloride and water a intermolecular force of an intramolecular bond?
The attraction between sodium chloride and water is an intermolecular force. It is specifically due to the electrostatic interactions between the charged ions in sodium chloride and the partially charged regions of water molecules.
What type of intermolecular force has water?
Hydrogens Bonds
Does water expand when heated and why?
Yes... When water is heated, the intermolecular force of attraction between water atoms become weak and they start losing the intermolecular force of attraction... at temperature known as boiling point of water this intermolecular force become so weak that water lose its state and converts into gasious state... but this expansion is not considerable... :)
What bond intermolecular force is found in water?
Hydrogen bonds
What force of a water molecule works against evaporation?
This is the intermolecular force of hydrogen bonds.
Is dissolving sugar in water a chemical property?
No, dissolving sugar in water is a physical property because it does not change the chemical composition of either the sugar or the water. The process involves breaking the intermolecular forces between sugar molecules, allowing them to mix with water molecules.
Explain why oil does not dissolve in water.?
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
Why water has this additional intermolecular force?
Hydrogen bonds between molecules
What type of bond attracts one water bond to another?
In pure water, the primary intermolecular force is a hydrogen bond, which is a specific type of dipole-dipole intermolecular force with notably more energy than most dipole-dipole intermolecular forces.
What intermolecular force gives water unique properties?
Hydrogen bonding is the intermolecular force that gives water its unique properties, such as high surface tension, cohesion, and adhesion. This force occurs between the hydrogen of one water molecule and the oxygen of another water molecule.
