"Calculate the total pressure of mixture of 1.05g of nitrogen gas, 3.66g of hydrogen gas, and 2.16g of chloring gas mixed in a sealed 3.6L container at 19°C"

your picture is not part of the scientific method.

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).
