A piece of marble chips was strongly heated in air for about 30 minutes. Some drops of water were added drop by drop to the product when it was still warm.
Using equation, explain:
(i) What happens when the piece of marble chips is heated?
(ii) The reaction that takes place when water is added to the final warm product.

i) It decomposes to give Calcium oxide/Lime and Carbon (IV) oxide
CaCO3_(s)------>CaO_(s) + CO_2(g)


ii) Alot of heat is evolved which makes the piece of lime swell hence the name quick lime and
Calcium hydroxide(slaked lime) is formed.
CaO_(s) + H₂O_(l)------>Ca(OH)_2(aq)

  Sodium metal tarnishes when exposed to the air where a white powder is formed on its
  surface. A small piece of this sodium metal was dropped into 25g of ethanol and 1200cm³
  of hydrogen gas was evolved at r.t.p. The unreacted ethanol was evaporated and a white
  solid remained. (Na=23, molar gas volume at r.t.p = 24dm³, C=12, O =16, H=1)
  (a) Write a chemical equation for the reaction between ethanol and sodium metal
  (b) Determine the mass of sodium that reacted with ethanol
  (c) What mass of ethanol evaporated?
  (d) The ethanol was evaporated at 80^oC, while the white solid remained unaffected at this
  temperature. What is the difference in structure of ethanol and the white solid?
  (II) (a) Name an inorganic liquid which liberates hydrogen gas with sodium metal
  (b) What two differences would you observe if similar pieces of sodium were dropped
  separately into small beakers containing equal amount of ethanol and the liquid
