Amixture of dry air and nh3 enters an absorption tower at 80 of and 740 mm hg with 95 % saturation. water was used to absorbed part of the nh3. the gas leaves the tower at 730 mm hg and 60 oe and contains 0.2 % mol nh3 and is saturated with water vapor the nh3 in feed is absorbed. calculate what % of vapor pressure of ammonia at 80 of is 50 mm hg

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).

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
