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.
Recent findings indicate that Indigenous Australians are probably descendants of the first modern humans to migrate out of Africa to Asia, roughly 70,000 years ago, arriving in Australia around 50,000 years ago. number of Indigenous people represent electorates at State and Territorial level and South Australia has had an Aboriginal Governor, Sir Douglas Nicholls. The first Indigenous Australian to serve as a minister in any government was Ernie Bridge, who entered the Western Australian Parliament in 1980.
