The other isotopes from mass 24 to mass 46 have been synthesized by appropriate nuclear reactions.All of these are radioactive with relatively short half-lives. Atomic weight, unlike the weight of an object, has nothing to do with the force of gravity. Phosphorus is found in smaller quantities in vegetables and fruit. TMDL stands for "Total Maximum Daily Load". Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and inflammatory shells. Phosphorus can be used in baking powder, fertilizers, and fireworks. Calculate the average flux density J of phosphorus downstream of the sewage pipe of example 2.1.The cross-sectional area of the river is 30 m.
