It is not recommended for use in temperatures in excess of 65 °C. [2] Alloy 5083 is also commonly used in cryogenic applications due to it being able to be cooled to -195°C. At this temperature, the alloy has an increase in ultimate tensile strength of 40% and in yield strength of 10% as well as exhibiting excellent fracture toughness at such ...

2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron, will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt, such as iron(II) sulfate: Fe (s) + H 2 SO 4 (l) → FeSO 4 (aq) + H 2 (g) There is some ambiguity at the borderlines ...
Aluminium acetate or aluminium ethanoate [1] (also "aluminum ~"), sometimes abbreviated AlAc in geochemistry, [2] can refer to a number of different salts of aluminium with acetic acid. In the solid state, three salts exist under this name: basic aluminium monoacetate , (HO) 2 AlCH 3 CO 2 , basic aluminium diacetate , HOAl(CH 3 CO 2 ) 2 , [ 3 ...

It is accurate enough to place 80 percent of its shots within a 40-foot (12.4 m) diameter circle from 4,000 feet (1,220 m) while in flight. [79] The GAU-8 is optimized for a slant range of 4,000 feet (1,220 m) with the A-10 in a 30-degree dive. [80] Front view of the A-10's GAU-8 installation. The aircraft's fuselage was designed around the cannon.
