参考答案:A, C
镍氢电池(NiMH)目前已经成为混合动力汽车的一种主要电池类型。NiMH中的M表示储氢金属或合金。该电池在充电过程中的总反应方程式是:
Ni(OH)2 + M =" NiOOH" + MH
已知:6NiOOH + NH3 + H2O + OH-="6" Ni(OH)2 + NO2-
下列说法正确的是
NiMH 电池放电过程中,正极的电极反应式为:NiOOH + H2O + e-= Ni(OH)2 + OH-
充电过程中OH-离子从阳极向阴极迁移
充电过程中阴极的电极反应式:H2O + M + e-=" MH" + OH-,H2O中的H被M还原
D.NiMH电池中可以用KOH溶液、氨水等作为电解质溶液
A narrowing of your work interests is implied in almost any transition from a study environment to managerial or professional work.
