when water vapor condenses it quizlet
What happens when water vapor condenses to a liquid? Co...
A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength.
Are ionic compounds easy to bend?
Ionic compounds are very easy to bend. … The bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a poor conductor.
Why is nacl brittle?
Sodium chloride crystals are brittle
Imagine what happens to the crystal if a stress is applied which shifts the ion layers slightly. Ions of the same charge are brought side-by-side and so the crystal repels itself to pieces!
What must happen for an ionic compound to dissolve?
When you immerse an ionic compound in water, the ions are attracted to the water molecules, each of which carries a polar charge. If the attraction between the ions and the water molecules is great enough to break the bonds holding the ions together, the compound dissolves.
How do ionic compounds dissolve into a solution that conducts electricity?
This is because when a salt dissolves, its dissociated ions can move freely in solution, allowing a charge to flow. The resulting solution will conduct electricity because it contains ions. … Only compounds that dissociate into their component ions in solution qualify as electrolytes.
Why do some ionic compounds not dissolve in water?
But some ionic compounds do not get dissolved in water. This is because the ionic forces in those molecules are very high, which creates high lattice energy. Due to high lattice energy, the hydration energy decreases that makes those compounds insoluble in water. … Hence, all ionic compounds are not soluble in water.
Why do ionic compounds have high conductivity?
Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds.
What makes an ionic compound more conductive?
Compounds with Strong Conductivity
The higher the concentration of ions, the greater the conductivity. Table salt, or sodium chloride, is an example of a compound with strong conductivity. It dissociates into positively charged sodium and negatively charged chlorine ions in water.
How does dissolving an ionic compound in water increase electrical conductivity?
The solution that forms when an ionic compound dissolves in water can conduct electrical current because the ions are charged and able to move freely past each other.
Do ionic compounds have luster?
However, the solid form of an ionic compound is not nearly as good at conducting electricity as when it is dissolved in water. Additionally, metals have higher density than nonmetallic substances, and they often contain luster (which is when light reflects off of a substance).
Are ionic solids brittle?
Ionic solids are composed of cations and anions held together by electrostatic forces. Due to the strength of these interactions, ionic solids tend to be hard, brittle and have high melting points.
Why are ionic solids hard and brittle 12?
Ionic solids are generally hard and brittle, due to the presence of strong electrostatic forces of attraction of the ions in the highly ordered organized crystal lattice structure.
How do amino acids join together?
when joining two amino acids together cells carry out a chemical reaction between the amine group of one amino acid and the carboxylic acid group of the second amino acid. … the four atoms, nitrogen, hydrogen, carbon and oxygen that link the two amino acids together is called a peptide bond.
How do amino acids bond together?
