The hydration equilibrium constant at 25 Â°C is called K h, which in the case of carbonic acid is [H 2 CO 3 ]/[CO 2 ] â 1.7Ã10 â3 in pure water and â 1.2Ã10 â3 in seawater. Hence, the majority of the carbon dioxide is not converted into carbonic acid, remaining as CO 2 molecules.n aqueous solution, carbonic acid exists in equilibrium with carbon dioxide, and the concentration of H 2 CO 3 is much lower than the concentration of CO 2.
The Indigenous cultures of Australia are the oldest living cultural history in the world â they go back at least 50,000 years and some argue closer to 65,000 years. One of the reasons Aboriginal cultures have survived for so long is their ability to adapt and change over time.
There are several hundred Indigenous peoples of Australia; many are groupings that existed before the British colonisation of Australia in 1788.Before Anglo-Europeans, the number was over 400.Indigenous or groups will generally talk of their people (sometimes their mob) and their country .These countries [1] are ethnographic areas, usually the size of an average European country, with around 200 on the Australian continent at the time of European arrival.Within each country, people lived in clan groups: extended families defined by various forms of Australian Aboriginal kinship.hese countries [1] are ethnographic areas, usually the size of an average European country, with around 200 on the Australian continent at the time of European arrival.
