Silicone is generally nonreactive, and silicone polymers are biocompatible, so they're used in things that stay in prolonged contact with the body, such as prosthetics and some implants. Silicon is also used in liquid solutions of calcium or sodium silicate, the latter of which is an ...
What is sodium in the periodic table?Common but Vital:Sodium is a common element that is found in every living organisms as well as in many of the rocks on Earth and in the ocean. It is a very soft metal and highly reactive, meaning it forms compounds with many of the other elements...
Thermite process : When highly reactive metals such as Sodium, Calcium, Aluminium etc., are usedas reducing agents they displace metals of lower reactivity from thecom-pound. These are exothermic reactions. The amount of heat evolved is so large that the metals produced in molten state. ...
What is the difference between physical and chemical properties in science? Why does solid calcium conduct electricity but solid iodine does not? Which element is more reactive, Iodine or Astatine? Why does chlorine have a higher electronegativity value than krypton?
What type of element is lead? In other words, what is it classified as on the periodic table? What element is the most reactive in the periodic table? Explain why. Which of the following groups of elements are likely to have substances that have both metallic and non-metallic properties?
Sodium, calcium, potassium and magnesium are common electrolytes in sports drinks. Ensuring you’re consuming electrolytes helps your body avoid imbalances in these important chemicals while better hydrating itself, which can help you get over alcohol withdrawal symptoms quicker and more comfortably....
The process splits the salt into its elements, with the sodium combining with water to form sodium hydroxide and the chlorine produced as a gas. There are a number of simple ways of producing the element in the laboratory, for example, by the action of acids on sodium or calcium ...
As a more effective therapy for this common, often disfiguring pigmentary disorder is direly needed, we must strive harder to settle the pathogenesis debate definitively on the basis of sound experimental evidence, rather than by a war of dogmatic theories. Recognizing, however, that it is ...
