Boiling point of NH3: -33,34 0C
Boiling point of NF3: -129,1 0C
The boiling point of ammonia is higher.
Hydrogen fluoride has a higher boiling point -83,6 0C.
Sodium chloride has a higher boiling point.
Hydrogen fluoride has higher boiling point than hydrogen bromide ( HF 19.5 C HBr -66 C) because in hydrogen fluoride has two kinds of forces, one is hydrogen bonding and other is London dispersion forces. In Hydrogen bromide there are only london dispersion forces. These are weaker than hydrogen bonds therefore HF has the higher boiling pint.
Because after melting a substance must be heated further, to a higher temperature where the boiling is possible.
No. Once the substance crosses into steam the steam temperature can rise much higher than boiling.
No, Nitrogen is around -190 C and hydrogen is around -250 c.
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
Concentrated. concentrated solutions is completely ionized. The colligative property that is boiling-point states that it will increase as the number of particles increases. Diluting a concentrated substance lessens the number of particles making it obviously lower in bp
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
When an impurity is in a substance, the boiling point is raised. So water mixed with sugar will have a higher boiling point.
NO2 has a higher boiling point than CO2 because the nitrogen radii is larger than carbon. The bigger the atom the more intermolecular force that is created...this requires more energy to break causing a higher boiling point.
Higher boiling point will become vapor, then you have the other substance left over.
Typically, it decreases.
Because the hydrogen bonding in HF is much stronger than the intermolecular bonding in ammonia.
The more the substance, the longer and higher temperature it will take to melt/boil/freeze/condense.
Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
There is no definite pH for any acid or base as it depends as much on the concentration of the substance in a solution as the strength of the acid or base. Still, sodium fluoride is mildly basic so a sodium fluoride solution will have a pH higher than 7.
CBr4 is larger than CH4, so it has a higher London dispersion, a type of Intermolecular force. Higher force means longer time to bring the substance to boil, thus a higher boiling point.
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
Since oxygen has a higher electronegativity than nitrogen, the hydroxyl radical is more polar than the amide radical, and hence, creates a stronger electrostatic attraction between molecules and consequently a higher boiling point.
The boiling point will increase. The impurities essentially "block" the molecules of the substance from leaving the liquid as a gas, so a higher temp is needed to boil it. see colligative properties.
Calcium fluororide is ionic whereas chlorine fluoride is covalent.
