For example, if this is session 0, boxes 0-2-5-9, 1-3-6-0, 5-7-0-4, and 8-0-3-7 are done because they all contain the number 0. If a reviewed card isn't successful, it moves back to Deck Current. If a reviewed card is successful and the last number of its box matches the current session number, then that card moves to the Retired Deck.
Launch Area 3 contains two launch pads, Area 3 and Area 3A. Area 3 , also known as the Mk.I launcher , was used by eighteen Scout rockets between 1960 and 1964. The first launch from the complex, on 18 April 1960, was the maiden flight of the Scout launch vehicle, using the Scout X configuration.
La 2 O 3 + 6 NH 4 Cl → 2 LaCl 3 + 6 NH 3 + 3 H 2 O. This is followed by reduction with alkali or alkaline earth metals in vacuum or argon atmosphere: [17] LaCl 3 + 3 Li → La + 3 LiCl. Also, pure lanthanum can be produced by electrolysis of molten mixture of anhydrous LaCl 3 and NaCl or KCl at elevated temperatures. [17]

Lanthanum oxide is used in optical materials; often the optical glasses are doped with La 2 O 3 to improve the glass' refractive index, chemical durability, and mechanical strength. [8] 3 B 2 O 3 + La 2 O 3 → 2 La(BO 2) 3 [clarification needed] The addition of the La 2 O 3 to the glass melt leads to a higher glass transition temperature from ...

The colors of the γ-sesquisulfides are La 2 S 3, white/yellow; Ce 2 S 3, dark red; Pr 2 S 3, green; Nd 2 S 3, light green; Gd 2 S 3, sand; Tb 2 S 3, light yellow and Dy 2 S 3, orange. [60] The shade of γ-Ce 2 S 3 can be varied by doping with Na or Ca with hues ranging from dark red to yellow, [ 49 ] [ 60 ] and Ce 2 S 3 based pigments are used ...
