Using the standard entropy values: H2(g), S° = +130.6 J mol-1 K-1 I2(s), S° = +116.12 J mol-1 K-1 HI(g), S° = +206.0 J mol-1 K-1 calculate the standard entropy change, ∆S°, for the reaction: H2(g) + I2(s) → 2 HI(g)

the answers would be

the first one and the second one

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).
