Was Napoleon's death really due to stomach cancer, or was it arsenic poisoning? Some scientist believe the latter. Arsenic poisoning was a deadly weapon in that era, because it was undetectable when administered over a long period of time, making murder seem like natural causes. But if arsenic (As) is poisonous to most multicellular life, then what's with the newest NASA discovery?
Every day we pass bridges, whether it's a foot bridge, a highway overpass, a span over water, or a viaduct over a valley. We pass on these structures without even thinking of the engineering genius that went into their design and construction, let alone the science behind their strength.
Chemistry can be very fun when you create different kinds of reactions between elements. Note that caution should be employed to not harm yourself while performing these reactions. Ammonium Tricynate reacts with barium hydroxide octahydrate in endothermic form.
