Q:

Why is graphite a good lubricant?

A:

Quick Answer

Graphite is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant. This slippery quality also makes graphite a good material for pencil lead because it easily sloughs off onto paper.

Full Answer

Thanks to its chemical structure, graphite is a naturally slippery material that tends to crumble easily. Graphite is often contrasted with diamond, one of the hardest materials known to man, because both are made of carbon atoms arranged in a crystalline structure but with dramatically different results.

  • Q:

    What is the difference between alkane and alkene?

    A:

    Alkanes are hydrocarbons with single covalent bonds between the carbon atoms, while alkenes are hydrocarbons with one or more double covalent bonds between the carbon atoms. Hydrocarbons are either aliphatic or aromatic. Alkanes and alkenes are aliphatic hydrocarbons, which means they are both formed when oils or fats are degraded chemically.

  • Q:

    What are alkanes, alkenes and alkynes, and what are their uses?

    A:

    Alkanes are a class of organic chemicals that all have single bonds between carbon atoms, alkenes are organic compounds with at least one double bond between a pair of carbon atoms and alkynes feature at least one triple bond among carbon atoms. Uses for these types of compounds include gasoline, fuel, cleaners, food additives, plastic production and fuel for welding torches.
