Secondary porosity development (alarmingly called decompaction!) is thought to result from carbonate solution by carbonic acid formed by decarboxylation during early stage hydrocarbon generation.
Representative proteins that use catalytic zinc ions are carboxypeptidases, carbonic anhydrase, and alcohol dehydrogenase.
During this period microbial activity is at its lowest because of low soil temperatures and therefore the production of carbonic acid is likely at its minimum.
Out of that number there have been 233 cases in which it was found that there were twelve volumes of carbonic oxide in the air.
I do not like imbibing carbonic acid gas, either in mineral waters or in anything else.
Another thing is carbon dioxide, which is what we used to call carbonic acid gas, and it is very unpleasant.
The nostrils and mouths of human beings are such that one does not die from carbonic acid gas.
There you have apparatus that contains simply solid carbonic acid, and when you press the button out comes the stream of carbonic acid and combustion is impossible.
