Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
The history of the medications used in mental disorders has developed a lot through years. The discovery of modern drugs prevailed during the 20th century. Lithium, a mood stabilizer, was discovered as a treatment of mania, by John F. Cade in 1949, "and Hammond (1871) used lithium bromide for 'acute mania with depression'". [14]
Lithium toxicity, which is also called lithium overdose and lithium poisoning, is the condition of having too much lithium in the blood. This condition also happens in persons who are taking lithium in which the lithium levels are affected by drug interactions in the body.
Cold shock response is a series of neurogenic cardio-respiratory responses caused by sudden immersion in cold water. In cold water immersions, such as by falling through thin ice, cold shock response is perhaps the most common cause of death. [1] Also, the abrupt contact with very cold water may cause involuntary inhalation, which, if ...
Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. The order of reactivity, as shown by the vigour of the reaction with water or the speed at which the metal surface tarnishes in air, appears to be Cs > K > Na > Li > alkaline earth metals,
The reaction of quadricyclane with DEAD is a 2σ + 2σ + 2π cycloaddition that on water takes place within 10 minutes at room temperature with 82% yield. The same reaction in toluene takes 24 hours at 80 °C with 70% yield. An emulsion reaction in fluorinated cyclohexane takes 36 hours and the neat reaction takes even longer (48 hours).

The physical reactions to LSD vary greatly and some may be a result of its psychological effects. Commonly observed symptoms include increased body temperature, blood sugar, and heart rate, as well as goose bumps, jaw clenching, dry mouth, and hyperreflexia. In cases of adverse reactions, users may experience numbness, weakness, nausea, and ...
