Iam currently doing the test and i need . the decomposition of calcium carbonate, caco3(s) --> cao(s) + co2(g), has the following values for free energy and enthalpy at 25.0°c. g = 130.5 kj/mol h = 178.3 kj/mol what is the entropy of the reaction? use g = h – ts. a. -160.3 j/(mol. k) b. -47.8 j/(mol. k) c. 160.3 j/(mol. k) d. 1,912 j/(mol. k)

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

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).
