Brimstone is a ground or air-launched ground attack missile developed by MBDA UK for the UK's Royal Air Force. [9] It was originally intended for "fire-and-forget" use against mass formations of enemy armour, using a millimetre wave (mmW) active radar homing seeker to ensure accuracy even against moving targets.

Brimstone – sulfur; Flowers of sulfur – formed by distilling sulfur. Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash. Caustic Soda/caustic marine alkali – sodium hydroxide, NaOH, formed by adding lime to natron. Caustic volatile alkali – ammonium hydroxide.
Flowers of sulfur were traditionally produced by subliming naturally occurring sulfur, known as sulphur vivum.Impurities and moisture could cause acid residue in the product, so it was often washed, the result being known as "washed flowers of sulfur" (in Latin, flores sulphuris loti).
The RAF's Brimstone missile is a fire-and-forget anti-tank missile.. Fire-and-forget [1] [2] is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target.
The flame test carried out on a copper halide.The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample.
In chemistry, chemical purity is the measurement of the amount of impurities found in a sample. Several grades of purity are used by the scientific, pharmaceutical, and industrial communities. [1] [2] Some of the commonly used grades of purity include:
In NMR spectroscopy, e.g. of the nuclei 1 H, 13 C and 29 Si, frequencies depend on the magnetic field, which is not the same across all experiments. Therefore, frequencies are reported as relative differences to tetramethylsilane (TMS), an internal standard that George Tiers proposed in 1958 and that the International Union of Pure and Applied Chemistry has since endorsed.
