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.
Their culture is a mixture of Aboriginal from mainland Australia and that of Papua New Guinea, to their immediate north. In earlier times, this land formed part of the one land mass linking Papua New Guinea to mainland Australia.he longest continuing religion in the world belongs to Australia's Aborigines, with the Rainbow Serpent mythology recorded in rock shelter paintings believed to be 7,000 years old in the Kakadu National Park region, where this Ancestral Being is still important to local people.
