The mean absolute deviation is the average of the positive distances of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out). The MAD helps determine whether the set's mean is a useful indicator of the values within the set.
95 - 98+. Although Potassium only has two stable isotopes (K-39 and K-41), the long-lived radioisotope K-40 is often also regarded as a stable isotope. Potassium Isotopes, mainly K-40 and K-41, are used to study the impact of potassium on the growth of plants and of the human cardiovascular system.
Potassium permanganate, also known as permanganate of potash or Condy's crystals, is a chemical compound with a chemical formula of KMnO4, made of a potassium (K+) ion and a permanganate (MnO4-) ion.It is a strong oxidizing agent, so it readily takes or accepts electrons from other substances.It normally appears in the form of solid purple crystals and can dissolve in water to form a purple solution. Potassium permanganate, while not as well-known as other chemical compounds, has many uses.rganic and Analytical Chemistry. In organic and analytical chemistry laboratories, potassium permanganate is a very valuable reagent. In organic chemistry, potassium permanganate is used to synthesize and react with different organic compounds.
