Sodium triacetoxyborohydride, also known as sodium triacetoxyhydroborate, commonly abbreviated STAB, is a chemical compound with the formula Na[(CH 3 COO) 3 BH]. Like other borohydrides, it is used as a reducing agent in organic synthesis. This colourless salt is prepared by protonolysis of sodium borohydride with acetic acid: [1]

NaPb 3, NaPb, Na 9 Pb 4, Na 5 Pb 2, and Na 15 Pb 4 are some of the known sodium-lead alloys. Sodium also forms alloys with gold (NaAu 2) and silver (NaAg 2). Group 12 metals (zinc, cadmium and mercury) are known to make alloys with sodium. NaZn 13 and NaCd 2 are alloys of zinc and cadmium. Sodium and mercury form NaHg, NaHg 4, NaHg 2, Na 3 Hg 2 ...

The Avogadro constant, commonly denoted N A [1] or L, [2] is an SI defining constant with an exact value of 6.022 140 76 × 10 23 mol −1 (reciprocal moles). [3] [4] It is this defined number of constituent particles (usually molecules, atoms, ions, or ion pairs—in general, entities) per mole and used as a normalization factor in relating the amount of substance, n(X), in a sample of a ...
The voltage-dependence of steady-state fast inactivation is unchanged in Na v 1.1–Na v 1.4, but steady-state fast inactivation in Na v 1.5 is depolarized. Hence, among the sodium channels that have been studied so far, Na v 1.4 is the least and Na v 1.5 is the most proton-sensitive subtypes. [59]

For example, if a form contained a field for a middle name, and the person filling out the form put "N/A", the computer might interpret this as "N/A" being the person's middle name; this in turn might result in the person receiving mail from the company that produced the form with "N/A" where a middle name would normally appear.
