Chlorine atoms from cfc molecules speed the breakdown of stratospheric o3 in a process that is affected by both homogeneous and heterogeneous catalysis.

true or false?

False, just heterogeneous.

Explanation:

Hello,

Ozone layer degradation by the CFC molecules occur in gaseous phase since no liquids or solids are involved at those stratospheric conditions. In addition, that is a chemical reaction undergoing by itself as long as the ozone () is pretty much chemically unstable, so there is no necessity of a catalyst.

Best regards.

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).
