Molecular compounds have relatively high boiling points?
false they tend to have low boiling points
Why does water exist in liquid state?
At room temperature, water is in a liquid state because it has a high boiling point, as compared to gases that have relatively low boiling points.
What are the propeites of a molecular compound?
molecular compounds have relatively low boiling points but the bigger the molecult the bigger the boiling point (this is van der waals forces) If they are soluble in water, they are nonelectrolytes, because they do not produce and ions when dissolved in water. If they are solids, they tend to be soft, and they are nonconductors of electricity in solid form. Many are liquids or gases at room temperature. Examples include water, carbon dioxide, ammonia, alcohol, and sugar.
How is ammonia used as refrigerant?
Ammonia has a low boiling point, is cheap, largely available and energy efficient.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
Molecular compounds have relatively high boiling points?
false they tend to have low boiling points
Why the melting and boiling point of covalent compound are low?
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
Why does water exist in liquid state?
At room temperature, water is in a liquid state because it has a high boiling point, as compared to gases that have relatively low boiling points.
Liquid ammonia is used as a refrigerant because of its?
...because of its low cost, low boiling point, relatively high heat of vaporization and heat capacity.
Does ammonia have a higher boiling point than methane?
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
Ionic compounds have boiling points that are often above?
Ionic compounds have boiling points of
What is the boiling temperature for covalent compounds?
All different covalent compounds have different boiling points.
What is the boiling point of ammonium?
The boiling point of ammonia at atmospheric pressure is -33.34oC.
How do you separate ammonia from hydrogen?
by boiling the mixture
Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.
What is the meaning of melting point of ammonia and boiling point of ammonia?
The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius
