In chemistry, methanium is a complex positive ion with formula [C H 5] + (metastable transitional form, a carbon atom covalently bonded to five hydrogen atoms) or [CH 3 (H 2)] + (fluxional form, namely a molecule with one carbon atom covalently bonded to three hydrogen atoms and one dihydrogen molecule), bearing a +1 electric charge.
Form W-4, 2012. Form W-4 (officially, the "Employee's Withholding Allowance Certificate") [1] is an Internal Revenue Service (IRS) tax form completed by an employee in the United States to indicate his or her tax situation (exemptions, status, etc.) to the employer.

The notation convention chosen here (with W 0 and W −1) follows the canonical reference on the Lambert W function by Corless, Gonnet, Hare, Jeffrey and Knuth. [3]The name "product logarithm" can be understood as follows: since the inverse function of f(w) = e w is termed the logarithm, it makes sense to call the inverse "function" of the product we w the "product logarithm".
The molecular formula CH 4 N 2 O (molar mass: 60.06 g/mol, exact mass: 60.03236 u) may refer to: Urea, or carbamide; Ammonium cyanate; Formylhydrazine
Pan Am Flight 103 (PA103/PAA103) was a regularly scheduled Pan Am transatlantic flight from Frankfurt to Detroit via a stopover in London and another in New York City. Shortly after 19:00 on 21 December 1988, while the Boeing 747 "Clipper Maid of the Seas" was in flight over the Scottish town of Lockerbie, it was destroyed by a bomb, killing all 243 passengers and 16 crew in what became known ...

The compound is closely related and convertible to the industrially significant derivatives paraformaldehyde ((CH 2 O) n), formaldehyde (H 2 C=O), and 1,3,5-trioxane ((CH 2 O) 3). [3] Methanediol is a product of the hydration of formaldehyde. The equilibrium constant for hydration is estimated to be 10 3, [4] CH 2 (OH) 2 predominates in dilute ...
