The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
[2] [7] The heat of formation is c. 24 kilocalories (100 kJ) per mol. [7] It is a semiconductor with a reported bandgap of c. 3.2eV, [9] however, a thin zinc nitride film prepared by electrolysis of molten salt mixture containing Li 3 N with a zinc electrode showed a band-gap of 1.01 eV. [10] Zinc nitride reacts violently with water to form ...

Zinc azide is a coordination polymer which crystallizes in three polymorphs, all of which feature tetrahedral zinc centers and bridging azide ligands. α-Zn(N 3) 2 crystallizes in the monoclinic space group and is stable, while the other two polymorphs are metastable.
In its compounds, Zn 2+ ions have an electronic configuration [Ar] 3d 10.As such, Zn 2+ tends to have a symmetrical coordination geometry in both its complexes and compounds. In both ZnO and ZnS, zinc is bound tetrahedrally bound to four ligands (oxide and sulfide, respectively).
Cigarette smoke contains numerous other potentially cardiotoxic substances, including carbon monoxide and oxidant gases. [93] A 2016 review of the cardiovascular toxicity of nicotine concluded, "Based on current knowledge, we believe that the cardiovascular risks of nicotine from e-cigarette use in people without cardiovascular disease are ...
GLP-1 drugs used for weight loss involve all kinds of side effects—good and not-so-good—that may or may not strike the average user. (Reminder that there are many of these meds now.
A heated tobacco product (HTP) [note 1] is a tobacco product that heats the tobacco at a lower temperature than conventional cigarettes. [32] These products contain nicotine, which is a highly addictive chemical. [32] The heat generates an aerosol or smoke to be inhaled from the tobacco, which contains nicotine [33] and other chemicals.
