Answer:
Alchemy is generally seen as an archaic proto-science based on superstition that is of little interest to the modern chemist. ... In Western alchemy, perfection is achieved through the action of the Philosophers Stone. Alchemists believed that it could turn any substance into gold, prolong life and cure illness
Explanation:
Answer:
HF - hydrogen bonding
CBr4 - Dispersion
NF3 - Dipole-dipole
Explanation:
Hydrogen bonding occurs when hydrogen is covalently bonded to a highly electronegative atom such as fluorine, chlorine nitrogen, oxygen etc. Hence the dominant intermolecular force in HF is hydrogen bonding.
CBr4 is nonpolar because the molecule is tetrahedral and the individual C-Br dipole moments cancel out leaving the molecule with a zero dipole moment hence the dominant intermolecular force are the dispersion forces.
NF3 has a resultant dipole moment hence the molecules are held together by dipole-dipole interaction.
