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 extracted from the ground, however, take...
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 rea...
Explain why polystyrene is much more readily oxidized by O_2 in the air than polyethylene is. Which H's in polystyrene are most easily abstracted and why? What caused the granular polystyrene to form Styrofoam when it was placed in boiling water?
What is graphite? Is it conductive or not? Describe the chemical properties of table salt (NaCl). What is corrosion? Which of the six types of solids is salt? Explain how you know this based on the following: a. the formula of salt b. the properties of salt c. the intramolecular forc...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
This is a rather fine point that you should understand: although transfer of heat between the system and surroundings is impossible to achieve in a truly reversible manner, this idealized pathway is only crucial for the definition of ΔS; by virtue of its being a state function, the same val...
A kettle is a vessel designed for boiling liquids, characterized by its lid, spout, and handle, while a pot is a round, deep cooking container with handles and often a lid.
·2H2O=233.93, green hexagonal crystal. The relative density is 6.14, the melting point is 1370°C (anhydrous salt), and the boiling point is 2327°C (anhydrous salt). Insoluble in water, it reacts with concentrated sulfuric acid to release hydrogen fluoride gas. Prepared by the interaction...
Why It's Impossible For A Moon To Be Bigger Than Its Planet ByElias Nash Jose A. Bernat Bacete/Getty Images Have you ever noticed that the Moon looks bigger when it's nearest to the horizon? Although it might seem as though the Moon is closer at that point, it's only an optical ...
Which of these sets of minerals is not an example of polymorphs? (a) Gold and silver (b) Diamond and graphite (c) Calcite and aragonite. How does the size of particles in sediment affect groundwater retention? What is bituminous coal?
