What is a characteristic of MgBr2?

Physical Properties

The anhydrous MgBr2 is a white crystalline substance; hexagonal crystals; deliquescent; density 3.72 g/cm3; melts at 700°C; highly soluble in water (101.5g/100mL at 20°C); moderately soluble in methanol and ethanol (21.8 and 6.9 g/mL at 20°C, respectively).

Is BaS soluble in water?

BaS is soluble in water (decomposes) but is insoluble in alcohol. Barium sulfide is prepared commercially by heating barite (BaO) with coal or petroleum coke in a rotary kiln at 1000 °C to 1250 °C in an oxygen-free atmosphere.

What bond is formed when Mg and bromine combine?

Therefore, for the resulting compound to be neutral, two bromine anions must combine with one magnesium cation to form magnesium bromide (MgBr2).
