WebWhite phosphorus, P4, spontaneously bursts into flame in oxygen. if 6.5g of white phosphorus reacts with sufficient oxygen to form 11.54g of a phosphorus oxide, what is the empirical formula of this oxide? Suppose that a device is using a 5.00-mg sample of silicon that is doped with 1 × 10-5% (by mass) phosphorus. Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of light. Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phos…
