Elevations above 2.6 km (1.63 mi) on the planet Venus are coated with a shiny substance. A PbS element can be used to measure radiation in either of two ways: by measuring the tiny photocurrent the photons cause when they hit the PbS material, or by measuring the change in the material's electrical resistance that the photons cause. Example #3 - Write the formula for: iron(III) sulfide. γ = 90,00 ° Depuis le 1er janvier 2005, une directive européenne impose aux fabricants de vin d'apposer la mention « Contient des sulfites » sur l'étiquette des produits qui en contiennent entre 10 et 400 mg/litre. {\displaystyle F\ 4/m\ {\bar {3}}\ 2/m\,} This addition causes the creation of bonds in the ion, another feature sulfide ions do not have.
