When a hydrate is heated to high temperatures, what is generally the product?

anhydrous compound

Heating a hydrate leads to an endothermic reaction that produces a residue known as the anhydrous compound. This compound is different in structure, texture and even color in some cases, from its parent hydrate.

Warming a hydrate prompts an endothermic response that creates a buildup known as the anhydrous compound. This compound is distinctive in structure, surface and even shading now and again, from its parent hydrate.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
