填空题

第三代混合动力车，可以用电动机、内燃机或二者结合推动车轮。汽车上坡或加速时，电动机提供推动力，降低汽油的消耗；在刹车或下坡时，电池处于充电状态。

(1)混合动力车目前一般使用镍氢电池，该电池中镍的化合物为正极，储氢金属(以M表示)为负极，碱液(主要为KOH)为电解质溶液。镍氢电池充放电原理示意如图，其总反应式为：H2＋2NiOOH2Ni(OH)2

根据所给信息判断，混合动力车上坡或加速时，乙电极周围溶液的pH       (填“增大”、“减小”或“不变”)，该电极的电极反应式为               。

(2)Cu2O是一种半导体材料，可通过如图的电解装置制取，电解总反应为：2Cu＋H2OCu2O＋H2↑

阴极的电极反应式是                                                      。

用镍氢电池作为电源进行电解，当蓄电池中有1 mol H2被消耗时，Cu2O的理论产量为       g。

(3)远洋轮船的钢铁船体在海水中易发生电化学腐蚀中的       腐蚀。为防止这种腐蚀，通常把船体与浸在海水里的Zn块相连，或与像铅酸蓄电池这样的直流电源的       (填“正”或“负”)极相连。
