Theres just no way they could deal with that. He went on, Obviously, if you get drought indices like these, theres no adaptation thats possible. But lets say its not that severe. What adaptation are we talking about? Adaptation in 2020? Adaptation in 2040? Adaptation in 2060?
Deuterium oxide (D2O, where D is deuterium, the hydrogen-2 isotope) has an ion-product constant, Kw, of 8.9 x 10^-16 at 20 *C (degrees Celsius). Calculate [D+] and [OD-] for pure (neutral) D2O at this temperature.
