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.
Australian cinema has a long history and the ceremonies of Indigenous Australians were among the first subjects to be filmed in Australia â notably a film of Aboriginal dancers in Central Australia, shot by the anthropologist Baldwin Spencer in 1900.he life expectancy of Indigenous Australians is difficult to quantify accurately. Indigenous deaths are poorly identified, and the official figures for the size of the population at risk include large adjustment factors. Two estimates of Indigenous life expectancy in 2008 differed by as much as five years.
