1) carbon should have no free electron in its structure.Why it can conduct electricity? Ans: Carbon has o kind of structure. i)Diamond钻石& ii)Graphite石墨 i)Diamond钻石--- all carbon atoms are strongly bond tetrahedrally to form a giant covalent neork. There is no free e- ...
In recent years, the most significant gas and electricity price rises and cuts have been in reaction to changes in Ofgem’s energy price cap, which is reviewed and updated four times a year. But how can a cap change the prices suppliers are allowed to charge? The cap was first introduced...
Why can't electrolysis happen in solids? Why do electrolysis use electrical current? Explain briefly. Does copper conduct more electricity than platinum? Why or why not? What are the differences between diamond and graphite? Why would HF have a lower electrical conductivity than NaCl?
The fact that either of these processes leads to a collection of charged ions is central to the electrical conductivity of ionic compounds. In their bonded, solid states, molecules like salt don't conduct electricity. But when they're dissociated in a solution or through melting, theycancarry ...

Why do copper (II) sulfate crystals not conduct electricity? Do metals and nonmetals conduct electricity and heat? Explain. 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...
Which metals conduct the best?Above: Electron shells Gold (au), Silver (Ag), Copper(Cu) and Zinc (Zn). Logic would have one think that Gold is the best conductor having a single s-orbital electron in the last shell (above chart) ... so why are Silver and Copper actually better (...
The gas and electricity suppliers pass these additional costs onto customers through their energy bills. Each region is different, and that's in part down to the amount of energy they are able to generate and the price of generating that energy. As mentioned above, some regions can get their...
The sole purpose of electrical wire and cable is to conduct an electric current from one point to another, but if the cable starts to corrode, it can quickly become damaged and result in loss of performance. Any copper in wire can be susceptible to corrosion. While bare copper is fairly ...
Electrical plating is quick. The bath tends to be stable. It is usually inexpensive. So why use electroless plating? There can be real advantages! Electroless Plating Electroless copper spreads plating uniformly. In electroplating, coating thickness varies from point-to-point. ...
