2na+2h2o=2naoh+h2是氧化还原反应。氧化还原反应 （oxidation-reduction reaction）是化学反应前后，元素的氧化数有变化的一类反应。氧化还原反应的实质是电子的得失或共用电子对的偏移。 氧化还原反应是化学反应中的三大基本反应之一（另外两个为（路易斯）酸碱反应与自由基反应）。自然界中的燃烧，呼吸作用...
NaOH(aq)→ Na+(aq)+ OH-(aq) Na+(aq)+ OH-(aq)+ H(g)= H2O(l)+ Na(s) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation. ...
Balance the reaction of NaOH + H2Po4 = Na3 + Po4 + H2O using this chemical equation balancer!
可以在radfrac里，设定反应方程，这就要在系统组成里，添加na离子和hco3等离子， 具体的可以参考比较详细...
解答如下:2B+2NaOH+6H2O=2Na[B(OH)4]+3H2↑；简写为2B+2NaOH+2H2O=2NaBO2+3H2↑；和Al类似。注意NaBO2实际在溶液中也不存在。 所以，从氧化还原的角度来看 b是还原剂 h20是氧化剂哈亲亲。扩展:氧化还原反应 （oxidation-reduction reaction）是化学反应前后，元素的氧化数有变化的一类反应。
Here we report a membrane-free chlor-alkali electrolysis process, where the Cl2 evolution and H2/NaOH production are decoupled by the reversible Na-ion intercalation/de-intercalation reaction of the Na0.44MnO2 electrode. This decoupled strategy shows promise in developing a clean chlor-alkali technolog...
