P.B.

The campaign was known to palace insiders as “Operation Mrs. PB.”

Our children are now taught that a classmate might die right in front of them if they bring PB&J for lunch.

When the wire is free from twist, the magnetization at any point P is in the tangential direction PB (see fig. 26).

Lead is not a compound, but an element whose chemical symbol is Pb, taken from the Latin name for lead.

Now, similarly, at pB the sector B has come around and begins to pass behind P.

Dilute nitric acid readily dissolves the metal, with formation of nitrate Pb(NO3)2.

It dissolves in an excess of alkali to form plumbites of the general formula Pb(OM)2.
