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 300°C, a zircaloy cladding that protects the fuel rods is inert. However, above 1,200°C, 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.
