My question is, that it's asking us to tell whether the partial pressure of a molecule will increase decrease of remain the same and to show it by a calculation? I don't which calculation to use. I have V T P and grams. I don't know what equation to use to show my prediction.

PV=nRT

Explanation:

Assuming it is an Ideal gas, You are going to make Pressure here the subject of formula and input it into Dalton's law of Partial pressure. Ptotal = P1 + P2 + P3

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).
