					Two basic differences would be obviously innate size and structure.


       Diamonds -- as we know them as humans -- can be small, as small as 1/100th of a carat
        (one point) when processed. There may be smaller raw diamond stones, but they are
        generally commercially viable as industrial diamond dust.
       Nanotubes -- are 1/50,000th the width of a human hair, considerably smaller than a
        (commercial) diamond or perhaps even diamond dust grains.


       Diamonds are cubic in their structure and in raw form appear triangular or as two
        pyramids attached at the base.
       Nanotubes naturally align themselves as ropes.

Carbon Nanotubes Twice as Strong as Once Thought

ScienceDaily (Sep. 16, 2010) — Carbon nanotubes -- those tiny particles poised to revolutionize
electronics, medicine, and other areas -- are much bigger in the strength department than anyone
ever thought, scientists are reporting. New studies on the strength of these submicroscopic
cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger
than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other

Why is Copper a good conductor and how is it's structure different from
silicon and germanium?

The reason why copper is a good conductor is because there are a lot of free electrons that can carry the
flowing current efficiently. These free electrons do not remain permanently associated with the copper
atoms, instead they form an electron ‘cloud’ around the outside of the atom and are free to move
through the solid quickly.

It has a really high melting point because it is a macro molecule (giant molecule) and has very
stong bond

Blue diamonds do not conduct electricity. Diamonds do, however, conduct heat, in fact five times better
than silver.

Both diamonds and graphite are produced naturally from carbon. Diamond is an excellent electrical
insulator, graphite is a good conductor of electricity.

it forms four covalent bonds with other carbon atoms, meaning that all four of its valence (outer shell)
electrons are involved in bonding.

This means that there are no electrons free to carry the electric current, since all are involved in

Well recycling Cu can be advantageous as is is becoming an "rare" metal in its ore state. So if we dont
recycle then we wont have any copper left to mine. Recycling would make it more abundant in an
manner of speaking.

A disadvantage is that it costs a lot retrive and separate the copper from the waste it is used in to
recycle. Copper is used in cables due to its good electrical conductivity so its time and cost consuming to
get the copper from the wire itself.

                                  1. Reaction with alkalis.
    Carboxylic acids are neutralised by alkalis, for example
methanoic acid + sodium hydroxide        sodium methanoate +
HCO2H(aq) +      NaOH(aq)               HCO2Na(aq)     + H2O(l)

ethanoic acid + potassium hydroxide       potassium ethanoate
                         + water.
 CH3CO2H(aq) +       KOH(aq)               CH3CO2K(aq)     +

                 2. Reaction with carbonates.
  Carboxylic acids are neutralised by carbonates, for example
 ethanoic acid+sodium carbonate sodium ethanoate+carbon
   2CH3CO2H(aq) + Na2CO3(s)            2CH3CO2Na(aq)
                     + CO2(g) + H2O(l)

  butanoic acid + zinc carbonate    zinc butanoate + carbon
                       dioxide + water.
   2C3H7CO2H(aq) + ZnCO3(s)              (C3H7CO2)2Zn(aq)
                       + CO2(g) + H2O(l)
