Q1 - Written response question on Chemistry The 2011 Tōhoku
earthquake and tsunami natural disaster that occurred on 11 March
2011 triggered a tsunami that caused the flooding of the Fukushima
Daiichi Nuclear Power Plant. The loss of power to the nuclear
reactor cooling system resulted in runaway nuclear reactions,
reactor meltdowns, and hydrogen explosions that released
radioactive material into the environment. At normal operating
temperatures of approximately 300oC, a zircaloy cladding that
protects the fuel rods is inert. However, above 1,200oC, zirconium
metal reacts exothermically with water (steam) to produce hydrogen
gas and zirconium oxide.
a) In this reaction, does hydrogen get oxidised or reduced?
b) The hydrogen gas produced reacted with oxygen to form water.
Write a fully balanced chemical equation including appropriate
state symbols for the explosive reaction between hydrogen and
oxygen.
c) The hydrogen gas produced by the reaction between zirconium
and water is vented into a headspace measuring 1.5 m × 3.0 m × 4.0
m. The hydrogen gas pressure measured by pressure sensors within
the headspace was 12,200 atm while the hydrogen gas temperature was
600o The hydrogen gas then reacted explosively with oxygen forming
water. Using this information in conjunction with the hydrogen:
oxygen stoichiometric ratios determined from a fully balanced
chemical reaction in (b), calculate the volume of water (in litres)
produced. Show all your workings to gain full marks.
