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.
In 2006 about 31% of the Indigenous population was living in 'major cities' (as defined by the Australian Bureau of Statistics/Australian Standard Geographical Classification) and another 45% in 'regional Australia', with the remaining 24% in remote areas.he Indigenous population of Australia is much younger than the non-Indigenous population, with an estimated median age of 21 years (37 years for non-Indigenous), due to higher rates of birth and death. For this reason, age standardisation is often used when comparing Indigenous and non-Indigenous statistics.
