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.
Tell us and you could Win a Samsung Tablet. Aboriginal and Torres Strait Islander cultures have changed and developed over time. However, European colonisation of Australia brought very rapid changes to Aboriginal society and dramatically affected Aboriginal land and the ways people lived.Australia has always had a mix of cultures and people although not in the same way as it does today.Before 1788 Australia was populated only by the Indigenous people of Australia-Aboriginal and Torres Strait Islanders.he number of Aboriginal people has changed since European settlement because of the effects of removal of people from traditional lands and the impact of cities and towns on populations. In many ways Indigenous Australia was different in the past from what it is today.
