Let's look at two objects: diamond and graphite. They look very different, both in terms of color and in other physical properties. But yet, they are both made of the SAME element, i.e. carbon. If what we see depends ONLY on atomic transition, they both will look the same, because...
Why do covalent compounds not conduct electricity? Why is graphite a good conductor whereas diamond is not? (Both contain infinite lattices of covalently bound carbon atoms) Why does diamond have a lower entropy than graphite? Why do metals conduct heat and electricity?
Carbon alone forms the familiar substances graphite and diamond. Both graphite and diamond are made only of carbon atoms. Graphite is very soft and slippery. Diamond is the hardest substance known to man. If both are made only of carbon what gives them different properties? The answer lies in...
a) diamond has a crystal structure similar to ice b) diamond is made up of only carbon atoms c) the C-C bonds all have different bond lengths d) a rigid network of atoms that cannot move 4. Which statement best describes why graphite is soft?
Reason (R ): Entropy of graphite is greater than that of diamond. AA and R both are correct, and R is correct explanation of A BA and R both are correct,but R is not the correct explanation of A CA is true but R is false DA and R both are false.Submit ...
Why do extrusive rocks have small crystals? Why is the lithosphere important? Why is igneous petrology important? Why are metamorphic rocks formed by contact metamorphism? Why do crystalline solids form? Why is graphite used as a lubricant but not diamond?
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… ...
Explain why ionic solids do not conduct electricity in the solid state but are strong conductors in the liquid state and when dissolved in water. Is copper a ferrimagnetic material? Explain. Explain why graphite has a lower melting point than diamond even...
Explain why do different liquids have different viscosity? Explain why, when a thermometer is placed in hot water, the column of mercury first descends slightly and then rises. (a) Briefly cite the main differences between ionic, ...
Graphite deposits have been found elsewhere, but nothing close to the purity and quality of the English find. Due to the impurities in these other deposits, the graphite from these must be crushed into a powder to filter out the unwanted bits. Eventually, a method was found to use this pow...
