Introduction to Problem Solving Skills. What is Problem Solving and Why is it Important? The ability to solve problems is a basic life skill and is essential to our day-to-day lives, at home, at school, and at work. We solve problems every day without really thinking about how we solve them.
Nitronium tetrafluoroborate is an inorganic compound with formula NOBF. It is a salt of nitronium cation and tetrafluoroborate anion. It is a colorless crystalline solid, which reacts with water to form the corrosive acids HF and HNO.
Praseodymium is a chemical element with symbol Pr and atomic number 59. Praseodymium is a soft, silvery, malleable and ductile metal in the lanthanide group.It is valued for its magnetic, electrical, chemical, and optical properties.It is too reactive to be found in native form, and when artificially prepared, it slowly develops a green oxide coating.n the 1930s it was found (Beck) that praseodymium dioxide could be precipitated from KOH/NaOH eutectic melts, by oxidation by electrochemistry, or by sodium chlorate. This formed the basis of a small-scale laboratory purification method. The relatively pure free metal itself was not prepared until 1931.
