Considering a pond filled with Ethanol up to a level of 26 (m) as shown in the figure. If the open-ended manometer placed at the bottom of the pond shows a gauge pressure of 1 atm, what is the vacuum in (mm hg) at which the air is, over the ethanol?

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
