The solid in bottle melts at 150 degrees C ionic or molecular?
molecular-weak intermolecular forces mean that only a small amount of energy is required t break the bonds.
What have a lower melting points than ionic solids?
Covalent solids generally have lower melting points than ionic solids. This is because covalent solids are made up of discrete molecules held together by relatively weak intermolecular forces, whereas ionic solids are made up of ions held together by strong electrostatic forces. The weaker intermolecular forces in covalent solids require less energy to overcome, resulting in a lower melting point.
What type of intermolecular force is found in water molecules in ice?
weak intermolecular forces because dry ice with sublime
Which matter has the minimum inter molecular force?
Intermolecular forces are weak in gases.
Why gases show high compressibility?
The intermolecular forces in gases are very weak.
Why do molecular substances with weak inter-molecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
Does KCl have a higher boiling point than CO2?
KCl is an ionic substance (strong intermolecular forces) and CO2 is a non-polar covalent substance (weak intermolecular forces)
Why molecular substances with weak intermolecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
What regions are a hydrogen bond a weak attraction between?
Hydrogen bonds are the strongest intermolecular bond, as opposed to intramolecular bonds (ionic, covalent and metallic). They are therefore comparatively weak (these are what is broken when a substance becomes gaseous). Intermolecular bonds exist, as the name suggests, between molecules.
Why do substances made up of simple molecules have low points?
Substances made up of simple molecules have low melting points because there are strong bonds between the atoms in the molecule, but weak bonds holding the molecules together. Therefore, the intermolecular forces break fairly easily, due to the fact that they are weak and the covalent bonds making up the molecule do not break because they are strong. This means that, due to the weak intermolecular forces breaking down easily, simple molecular substances have low melting and boiling points.
Some substances evaporate more easily than other because they?
Pass from solid to vapor state
What does it mean for a substance to be a pure substances?
If a pure substance is volatile it means that it vaporizes readily at room temperature. This also means that the substance has weak intermolecular forces.
The solid in bottle melts at 150 degrees C ionic or molecular?
molecular-weak intermolecular forces mean that only a small amount of energy is required t break the bonds.
Is NaCl is a weak ionic bond?
Yes, NaCl is weak ionic bond.
What indicates the presence of weak intermolecular forces in a liquid?
The characteristic that indicates the presence of weak intermolecular forces in a liquid is a low heat of vaporization. Another characteristic that indicates the presence of weak intermolecular forces in a liquid is a high vapor pressure.
In a substance that sublimes the intermolecular forces of attraction are?
very weak.
Which is a property of all gases?
they are malleable
