(1) Diamond and graphite are two minerals with
identical chemical compositions, pure carbon
(C). Diamond is the hardest of all minerals, and
graphite is one of the softest. If their
compositions are identical, why do they have
such profound differences in physical
properties?
(2) silicon and oxygen together make up nearly
75 percent by weight of the Earth's crust. But
silicate minerals make up more than 95 percent
of the crust. Explain the apparent discrepancy.
(3) If you were given a crystal of diamond and
another of quartz, how would you tell which is
diamond?
(4) Would you expect minerais found on the
Moon, Mars, or Venus to be different from those
of the Earth's crust? Explain your answer.
(5) Quartz is Si02. Why does no mineral exist
with the composition Si03?
Describe the following :(i) The role of cryolite in electro metallurgy of aluminium.(ii) The role of carbon monoxide in the refining of crude nickel.
Which of the following statements are true?(a) Both nitrogen and phosphorus can form a pentafluoridecompound.(b) Although CO is a well-known compound, SiO does notexist under ordinary conditions.(c) Cl2 is easier to oxidize than I2.(d) At room temperature, the stable form of oxygen is O2,whereas that of sulfur is S8.
