Properties that affects the melting and boiling points of a molecule?
The melting point and boiling point of a substance come under the category of phase changes. And the temperature at which these phase changes occur are related to the intermolecular forces holding the molecules of the substance together.
How do you calculate melting points and boiling points by using enthalpy and entropy?
The melting point and boiling point of a substance are related to its enthalpy of fusion and vaporization, respectively, and its entropy of fusion and vaporization. The melting point is where the solid and liquid phases are in equilibrium, while the boiling point is where the liquid and vapor phases are in equilibrium. By analyzing the balance between enthalpy and entropy changes during phase transitions, you can predict and calculate melting and boiling points.
What is the difference between inorganic and organic compound?
In general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions).
What might have happened if you are measuring the melting point and the compound disappears?
It could have sublimed... and turned directly from a solid into a gas instead of melting first. Compounds such as iodine, carbon dioxide and others do this readily.See the Related Questions to the left for more information about sublimation.
Why strontium bromide has high melting point?
Strontium bromide has a high melting point due to the strong ionic bonds between the strontium cations and bromide anions in its crystal lattice structure. These bonds require a significant amount of energy to break, resulting in a high melting point.
How melting and boiling point are related to stability of a compound?
Thermally unstable compounds are decomposed before melting or boiling.
What are three physical properties of ionic compounds that are associated with ionic bonds and related them to bond strength?
These are melting point, boiling point, hardness.
What is the difference the melting point of organic and inorganic compounds?
Generally, organic compounds have lower melting points compared to inorganic compounds due to weaker intermolecular forces such as van der Waals forces in organic compounds. Inorganic compounds tend to have higher melting points because of stronger ionic or covalent bonds between their atoms.
Does magnesium sulfate have a high melting point?
Magnesium sulfate has a high melting and boiling point, as it is made of Ionic bonds which are very strong. A lot of energy is needed to break them. So ionic compounds have high melting and boiling points. See related link for more information.

The properties of both ionic and molecular compounds are related to the?
The properties of both ionic and molecular compounds are related to their chemical bonding. Ionic compounds have strong electrostatic interactions between positively and negatively charged ions, resulting in high melting points and conductivity when dissolved in water. Molecular compounds have covalent bonds between atoms and tend to have lower melting points, are usually not conductive, and can exist as gases, liquids, or solids at room temperature.
What is the relationship between molar density and the physical properties of a substance?
The molar density of a substance is a measure of how tightly packed its molecules are. It is related to the substance's physical properties such as its melting point, boiling point, and density. Generally, substances with higher molar density tend to have higher melting and boiling points, and are denser.
What is the melting point and boiling point of gold?
Melting point: 1337.33 K, 1064.18 °C, 1947.52 °F Boiling point: 3129 K, 2856 °C, 5173 °F There is a related link below for more data on the metal we know as gold (Au).
How are the three properties of ionic compounds and ionic bonds the same?
The three main properties of ionic compounds - high melting and boiling points, conductivity in aqueous solutions, and brittleness - are all a result of the strong electrostatic forces holding the positively and negatively charged ions together in the crystal lattice of the compound. These properties are directly related to the strong ionic bonds that form when electrons are transferred from one atom to another.
