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 the first half of the twentieth century, right up until the 1960's, the Australian government sought to create a single, uniform white Australian culture. In the first half of the 20th century it was commonly thought that Indigenous people in Australia would inevitably die out.n the first half of the twentieth century, right up until the 1960's, the Australian government sought to create a single, uniform white Australian culture.
