PLEASE HELP The hydrogenation of unsaturated hydrocarbons is an important industrial process. Precious metals,

such as platinum and palladium, can greatly

increase the rate of this reaction. During this

process, the gaseous reactants are pumped

across a layer of metal powder. An example of this

process is shown below.

Describe how the metal probably increases the

reaction rate, identify whether this is an example

of homogeneous or heterogeneous catalysis, and

explain how you know.

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).
