Why is the dissolution of ammonium chloride an exothermic reaction?
The dissolution of ammonium chloride is an exothermic reaction because it releases energy in the form of heat. When ammonium chloride crystals are dissolved in water, the intermolecular forces between the ions and water molecules are stronger than the forces within the solid crystal lattice, resulting in the release of energy as heat.
What type of weathering causes the formation of an underground cave?
This would usually be caused by the dissolution of soluble rocks such as limestones. Dissolution is a chemical weathering process.
Which fundamental force contributes to pressure in both water and the atmosphere?
The fundamental force that contributes to pressure in both water and the atmosphere is gravity. Gravity causes the weight of the water or air above a certain point to exert a force downwards, which leads to pressure at that point.
When ammonium chloride dissolves what happen to the temperature?
The temperature of the solution will decrease. The dissolving of NH4Cl in water is endothermic.
Is limestone dissolved by carbonic acid chemical or mechanical?
The dissolution of limestone by carbonic acid is a chemical process. Carbonic acid reacts with the calcium carbonate in limestone to form calcium bicarbonate, which is soluble in water. This chemical reaction causes the limestone to dissolve.
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.
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.
Why water has this additional intermolecular force?
Hydrogen bonds between molecules
What force of attraction is responsible for the dissolution of an ionic crystal in water?
The force of attraction responsible for the dissolution of an ionic crystal in water is the electrostatic force between the ions in the crystal and the water molecules. Water molecules surround and solvate the ions, causing them to break apart from the crystal lattice and become dispersed in the water.
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 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.
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.
Why the dissolution of gases in water is virtually always exothermic?
Dissolution of gases in water is usually exothermic because the strong intermolecular forces in water (hydrogen bonding) help stabilize the solute molecules in the solution, releasing energy in the form of heat. The breaking of intermolecular forces within the gas molecule and the formation of new intermolecular forces with water leads to a lower energy state, resulting in an exothermic process.
