Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of other's opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow
题型4 陌生电池的工作原理分析
4.最近,科学家研发了“全氢电池”,其工作原理如图所示。下列说法不正确的 是C
A.右边吸附层中发生了还原反应 B.负极的电极反应是 H2-2e-+2OH-=2H2O C.电池的总反应是 2H2+O2=2H2O
D.电解质溶液中
Na+向右移动,
ClO

向左移动
谢谢
居敬持志,循序致精
其电极反应式为O2+4e-+4H+=2H2O 碱性及中性溶液:O2-与H2O结合,生成OH-,
其电极反应式为O2+4e-+2H2O=4OH-
熔融碳酸盐中:O2-与CO32-不能结合,只能和CO2结合生成CO32-, 其电极反应式为O2+2CO2+4e-=2CO32-
允许O2-通过的高温固体: O2+4e-=2O2-
负极: H2-2e- +CO32- =H2O +CO2
正极: O2+4e- +2CO2 = 2CO32-
