Probably sodium Na because it has a similar atomic mass and number
the formula of the heavy water is D2O
Answer:
it killed an extremely late amount t of people and destroyed Pompeii I believe
Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth's tectonic plates and allowing them to move.
(Missing in the question) solubility in g per 100 mL of water:
CdI2 86.2 (cold water) so,
-We will heat a saturation solution of CdI2 [86.2 g / 100 mL], by the effect of the heat the solution will be unsaturated and dissolve more CdI2 when reaching a high temperature. and let the solution cools again by itself and covers it well to make sure there is no dust in it. when it reaches back to the cold water temperature, we will find the solution is supersaturated and all the solute will stay dissolved.
