3.7 unorganic carboncompounds

What are inorganic compounds:

a COMPOUND

Examples of inorganic carbon compounds

carbondioxide, carbonic acids. Carbonates, calcium carbonates

Atmosphere

where carbondioxide gass is made

Unorganic compunds, in the atmosphere

carbon gass.

Carbondioxide gass in the atmosphere

unatural- combustion of fossil fules, absorbs electromagnetic radiation

How carbondioxide gass absorb long electromagnetic radiation

CO2-molecule can absorb heatradiation -> the energy increases the rotation and vibration of the molecule. +

Ocean -

how carbonic acid is made

Unorganic compunds, in the ocean and rainwater

carbonic acids, hydrogencarbon-ions, carbon-ions.

The pH of rainwater

5.6

Carbonic acid formula

H2CO3

Creation of carbonic acid

Carbon acid when dissolved in water

disociates the H+ -ions in steps. (The reactions can og both ways) +

The prosses when the carbonic acid turns into HCO3- and water

(hydrogencarbonation) The prosses when the carbonic acid truns into CO32-

Consequences of ocean acidification

interupts the DYNAMIC of the aquatic enviroments

Cause for struggle of marine life

increasing CO2 - consentrations make the ocean acidic,  lack of available calcium-ions and carbonate-ions disolves calcium to make acidic water, and the marine has no calcium-ions and carbonate- ions to extract to form calcium carbonate for the shells and skeletons -> fragile shelled animals, corals

Example of shellfish that struggle with acidification

pteropod, tiny sea creature (size of a pea), major food source. When put in sea water reflecting the pH and carbonate levels for the year 2100 -> their shell nearly disapears. +

How does the marine life struggle with thinning shells?

to many hydrogen ions and not enough molecules for them to bond with -> breaks the existing calsium carbonate molecules apart and disolving shells.

Unorganic compunds, in the"litosfæren"

kalkstein (limestone) a sedimentary rock with calsium carbonate, form dead fosils

Where does kalk in the "litosfæren" come from

shellfish, plankton, corals.

What does kalk consists of

CaCO3, a salt of calsium-ions (Ca2+) and carbon-ions (CO32-)

What is limestone used for

production of cement and concrete.

If limestone goes unto high pressure

it does from sedimentary to metamorfic, becomes marmor=marble
