A student ran the following reaction in the laboratory at 546 K: COCl2 (g) CO (g) + Cl2 (g)

When she introduced 0.723 moles of COCl2 (g) into a 1.00 liter container, she found the equilibrium concentration of Cl2 (g) to be 3.38×10-2 M.

Calculate the equilibrium constant, Kc, she obtained for this reaction.

Kc =

 For the reaction 2HCl(g) ==> H2(g) + Cl2(g), the Keq = [H2(g)][Cl2(g)]/[HCl(g)]^2

Explanation:

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).
