However, the excess phosphorus is susceptible to loss through runoff and erosion and can promote algal growth in freshwater systems causing the degradation of water quality. It is always a good practice to check the status of phosphorus in soil through regular soil testing before applying phosphorus fertilizers. Study with Quizlet and memorize flashcards containing terms like 1) In the following list, only __________ is not an example of matter. If added water, it can again turn into nitric acid. Headache, convulsions, delirium, coma, cardiac arrhythmias, and cardiovascular collapse may occur. Phosphorus pentachloride is used as a chlorinating agent in many organic syntheses, such as production of alkyl and acid chlorides. It is also a powerful oxidizing agent, converting non-metal elements to either the oxide or oxoacid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.

It is also a powerful oxidizing agent, converting non-metal elements to either the oxide or oxoacid. Experts are tested by Chegg as specialists in their subject area. Group 13 (Boron Group) Elements. Figure 2. Precipitation on the other hand is a process bywhich metal ions such as Al3+ and Fe3+ (these ions are dominant in acidic soils) and Ca2+ (dominant in calcareous soils) react with phosphate ions present in the soil solution to form minerals such as Al-, Fe-, or Ca-phosphates. 1) mercury (II) oxide is broken down into its elements by heating.
