Answer:
The formula used to calculate heat of fusion:
q = m·ΔH f
Explanation:
The formula used to calculate heat of fusion:
q = m·ΔH f
Answer: The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area. The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds. Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces. Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force.
Hope this helps.. Stay safe and have a Merry Christmas!!!!!!!!!! :D
Answer:
Salt is the pure substance out of them all.
Universal indicators are unsuitable for indicators because it has a range of colors.
basically, it changes from pink in alkali to colorless acid.
