Web3 jul. 2024 · The melting and boiling points of BaF 2 are 1368°C and 2260°C, respectively. Barium fluoride’s density is 4.89 g/cm³ while its molar mass is 175.34 g/mol. It is partly soluble in water. Its prolonged exposure to moisture can degrade its UV range transmission. BaF 2 can be corroded by moisture but in a dry environment can be used up to 800 o C. Webcompounds have the highest boiling points. CH 3CH 2OH has more dispersion forces than CH 3OH, so it has the highest boiling point. • Melting points of the hydrogen halides increase in the order HCl < HBr < HF < HI. Explain this trend. 2 There are two competing intermolecular forces at play:
