Why is graphite a good conductor whereas diamond is not? (Both contain infinite lattices of covalently bound carbon atoms) What are atoms and why are they important? Explain why metals conduct electricity. Explain the origin of the ``chemical shift" seen for a p...
B) Why does live wire have a higher voltage than the earth/neutral wires? Why do electrolytes conduct electricity? How does the type of wire affect resistance in a wire? Why is metallic bonding important? Why does a circuit need capacitors? What is their purpose? Why ...
Diamond and graphite are two well-known allotropes of carbon, each with distinct physical and chemical properties. However, despite these differences, there are notable similarities between the two structures. This article explores the commonalities, shedding light… ...
This gap is small enough that at room temperature, some electrons can acquire enough energy to jump from the valence band to the conduction band, creating a flow of charge and allowing the material to conduct electricity. On the other hand, in conductors, the valence and conduction bands ...
Explain why graphite has a lower melting point than diamond even though both are carbon compounds. What does the melting point tell you about the purity of a substance? Explain very briefly why the boiling point of H2O is higher than that of H2. Explain why the boiling points of the compon...
Why does graphite conduct electricity but diamond does not, yet they are made up of carbon? In terms of structure, explain why a water solution of salt conducts electricity but a water solution of sugar does not. Why is water a poor conductor of electricity? Explain why chemical compounds te...
Why does the molten sodium chloride conduct electricity, but the solid form of sodium chloride does not? In terms of structure, explain why salt has a higher melting point than sugar. Explain why graphite has a lower melting point than diamond even though both are carbon compounds. ...
Why does the solubility of a gas in an inert solvent decrease when heating? Why does diamond have a lower entropy than graphite? Discuss why we see an increase in boiling point with larger alkane molecules Explain how the temperature in a Bunsen burner can be increased? E...
Does the temperature in a piece of matter increase or decrease if the average energy per particle increases? Ice has a(n) ___ entropy than that of liquid water. 1. lower 2. equal 3. higher 4. can not tell What is the name of material that can be deformed permanently by...
Does solid NaCl conduct electricity? Explain why or why not. Why does graphite conduct electricity but diamond does not, yet they are made up of carbon? Why would a 1 M solution of MgSO4 have greater conductivity than a 1 M solution of NaCl when dissolved in water, and would it b...
