Answer:

The correct answer is glassy.

Explanation:

Obsidian, or also known as volcanic glass, is a type of igneous rock (volcanic rock belonging to the silicates), formed by aluminum silicates and a large percentage of silicic oxides.

The obsidian is formed when a volcano emerges lava that cools quickly, which has a minimum growth of crystals. In the flows where it is obtained, the high silica oxide content induces a high viscosity and degree of polymerization of the lava. The inhibition of atomic diffusion in this highly viscous and polymerized lava explains the lack of crystal growth, giving shape to the glassy texture.

Have a nice day!

What type(s) of intermolecular forces exist between two molecules of hexane? (BLB Ch. 11)
kati45 [8]

Answer:

induced dipole-dipole forces or London Dispersion forces / van der Waals forces.

Explanation:

Hexane is non-polar in nature. This is due to :

The bond in the molecule is C-H, which is non-polar in nature because the carbon and the hydrogen having very similar electronegativity values.

Hexane is also symmetric.

The intermolecular force acting in the molecule of the hexane are induced the dipole-dipole forces or London Dispersion forces / van der Waals forces.
