H 2 S so water has the higher melting point. Au will have it. Li has few electrons in the bonding levels so melts easily. I 2 only dispersion forces CsI melts higher. H 2 O 2 will be more soluble in water.
Hexane has no structures on it.
Lithium Chloride is ionic and in water the ions will be surronded by water molecules and held by ion-dipole forces. Using the freezing point depression the molality is 0.0005. C circle and dumbbell intersect to increase e density between atoms dumbbell and larger dumbbell with decrease in e density between atoms. There are the same number of valence electrons - 14. This molecule could have two possible versions.
