日本核反應堆爆炸的氫氣是從那裏產生的?

當氫與氧react會做成水 . 2H2 + O2 ------> 2H2O + energy
This is exothermic reaction , give out energy .
但當水受高温會將水split into 氫及氧 .
水 +高温(由核能產生) -------->氫 + 氧 . Just reverse the above reaction .水是用來cool 核蕊 , 現在水因抽水機壞了 , 不能circulate帶走熱力 , 而自已吸了熱能 , 化為蒸氣 , 當温度再升時 , 水分裂成氫及氧 , 而引起爆炸 .

Knowledge:
Kc depends on temperature.
under very high temp. ---- not 100 or 200 degrees, but >2000 degrees, everything is possible.

Ah Hin:
NOT electrolysis! though it's power plant, now there's no electricity.
(if there's free chlorine, the situation would be even more disastrous..)

普通將水電解(electrolysis)就會出hydrogen同埋oxygen..
但因為而家日本政府無晒其他方法..唯有用海水去冷卻果個核反應堆...
而當海水電解(electrolysis)既時候...就會有chlorine同埋hydrogen(氫氣)釋出黎...
而氫氣就係呢個時候出黎

Is it really possible to split into hydrogen and oxygen at the high temperature of water?

Suppose it is possible, the products formed may be very small. Just using the idea from chemical equilibrium, the Kc for conversion of H2O into H2 + O2 is 1.1 * 10^-81 mol dm^-3, which indicates the decomposition of water takes place to only a very small extent...
