Why is carbon black more electrically conductive than activated carbon? Why is it possible for a bird to sit on a high-voltage wire without being electrocuted? Why is a magnetic field produced due to a current? Why are surface currents important? What is the reasoning b...
Graphite is made up of carbon atoms, which have four free electrons and are able to form four covalent bonds. Graphite is a good conductor because of the way its layers are stacked and how they bond together. Graphite is a common material used in brake linings....
For the solid tantalum capacitors used in the demonstration, the pellet then receives successive coatings of manganese dioxide, graphite, and silver to form the cathode of the capacitor. This coated pellet is then packaged in a casing with external leads attached to the anode and cathode....
Carbon is a plentiful and versatile element. It can combine in ways that create compounds as hard as diamond, or can combine to make slippery substances like graphite. It is the sixth most abundant element present in the entire universe. ...
Why can graphite conduct electricity? Why is seawater a better conductor of electricity than water from a freshwater lake? Explain why diamond is an electrical insulator and graphite is an electrical conductor. Why is water a poor conductor of electricity? Why do covalent compounds not conduct...
Why is energy released when bonds are formed? Give reasons as to why graphite conducts electricity. Explain why non-ionic compounds, such as ethanol or sugar, are soluble in water. Would distilled water conduct electricity? Why or why not? Why do some substances not dissolve in water at all...
Why can graphite conduct electricity? Why does the centrifuge tube need to be filled with ice when performing a sublimation? Why do covalent compounds not conduct electricity? Why is shielding vital in the design of glass electrodes that have an internal resistance of 106 ohms...
Semiconductor: Semiconductors are objects in which the flow of current is not conserved. Similarly, those objects that allow the flow of current are called conductors. These semiconductors are the intermediates between conductors and insulators regar...
Why is graphite used as a lubricant but not diamond? Why is graphene flexible? Why are electrodes often made from graphite? Why is carbon black more electrically conductive than activated carbon? Why do metals reflect light? Why does a rocket engin...
Covalently bonded materials have covalent bonds between their atoms. The covalent bonds are formed when electrons are shared by the atoms of two non-metals (either same or different). Answer and Explanation:1 In ionically or metallic bonded materials there are ...
