Graphite and diamonds are made up of carbon atoms. Graphite, however, is soft and can be used to write with while diamonds are the hardest substance known to man and are the only substances that can be used to cut other diamonds. What is the main reason for this...
the anode is made of graphite, and the cathode material is a mixed oxide oflithiumand other metals, such as lithium cobalt(III) oxide. The electrolytes are used as transmitters of lithium ions from the cathode to the anode and back, depending on whether the cell...
Graphene is a material that is extracted from graphite and is made up of pure carbon, one of the most important elements in nature and which we find in daily objects like the lead of a pencil. Graphene stands out for being tough, flexible, light, and with a high resistance. It's calcu...
Is water an opaque substance? What chemical elements is glass made of? Which of the physical properties of water prevents it from overflowing the glass even though the water is above the rim?\\A. Density\\ B. Surface tension\\C. Natural pH\\D. Boiling point ...
In lithium-ion batteries, the negative electrode is made of graphite, a form of carbon, the positive electrode is made of a metal oxide, such as lithium cobalt oxide, and the electrolyte is a lithium salt dissolved in an organic solvent. The movement of lithium ions between the electrodes ...
Graphite is derived from a Greek word called graphene which means writing so it’s because graphite was primarily used initially for making pencils that’s how it got its name. is an aloe trope of carbon which is greyish in colour and opaque. It’s extra
When fractured, it is grayish in colour – hence the name (specifically, a fracture will follow along the graphite flakes which are gray). The low cost of production and attractive properties make gray iron one of the most commonly used ferrous alloys....

Think about it: The wood might come from trees in Oregon. The "lead" (which is actually graphite) could be from Sri Lanka. The metal part might have bits from Africa. The rapeseed oil used in the eraser might have come from Indonesia. ...
