Explain why diamond is an electrical insulator and graphite is an electrical conductor. Explain why copper possesses a high electrical conductivity. Why do metals conductivity rate reduces with increase in temperature? Why do metallic compounds conduct electricity as a solid? How do cond...
So why is graphite different to diamond? The atoms inside the two materials are arranged in different ways, and this is what gives the two allotropes their completely different properties: graphite is black, dull, and relatively soft (soft and hard pencils mix graphite with other materials to ...
To explain why ionic solids conduct electricity in the molten state but not in the solid state, we can break down the reasoning into several steps:1. Understanding Ionic Solids: Ionic solids are composed of positively and n
The electrode that will be plated is generally made from a cheaper metal or a nonmetal coated with a conducting material such as graphite. Either way, it has to conduct electricity or no electric current will flow and no plating will occur....
Explain why graphite has a lower melting point than diamond even though both are carbon compounds. Describe the bonding in metals and discuss how this explains high electrical conductivity. Explain why some ionic compounds are soluble in water. Does CO2 or SO2 have a lower boiling poin...
Why does not NaCl(s) conduct electricity? How is diffusion used in the manufacturing of semiconductor materials? Explain the differences between graphite and diamond as types of allotropes of carbon. Describe in detail the manufacture of Silicon crystals. Describe the process, equipm...
AFMs don't suffer from this problem because, although they use still tuneling, they don't rely on a current flowing between the specimen and a probe, so we can use them to make atomic-scale images of materials such as plastics, which don't conduct electricity. Photo: A typical atomic ...
"You don't generate your own electricity. Why generate your own computing?" Jeff Bezos, Amazon. What's good and bad about cloud computing? Advantages The pros of cloud computing are obvious and compelling. If your business is selling books or repairing shoes, why get involved in the nitty ...
Question: Explain why covalently bonded materials are generally less dense than ionically or metallic bonded materials. Covalent Bonds: Covalently bonded materials have covalent bonds between their atoms. The covalent bonds are formed when electrons are shared by the ...
Explain why graphite has a lower melting point than diamond even though both are carbon compounds. (a) Why do many organic compounds have low melting and boiling points? (b) Some organic compounds, like table sugar, do not have a boiling point. Suggest a reason why. How ...
