I was reading Shirley Hazzard’s novel The Transit of Venus. Though I (51) her other books, I had always resisted this one. It (52) me as too pure somehow, too heroic, larger or finer than life and therefore unreal. But now I read it with an almost (53) pleasure. There were sentences that (54) of gratification to my eyes and (55) the hairs on the nape of my neck. I was in a Boston hospital, propped tip in bed with a feeding tube in my arm after (56) surgery for cancer. It was

填空题

某火电厂的脱硫尾气通入饱和K2CO3溶液吸收池后，经分解池制得纯净的CO2，再在合成塔与H2反应生成甲醇。其工艺艺流程示意图如下:

（1）吸收池中饱和K2CO3溶液吸收CO2的离子方程式是                          。

（2）流程示意图中循环使用的物质是                        。

（3）300℃时，合成塔中的反应为CO2(g)＋3H2(g)CH3OH(g)＋H2O(g)，在密闭条件下，下列示意图能说明反应进行到t1时刻时达到平衡状态的是         (填字母序号)

（4）利用合成塔中失活后的铬锌触媒可制得含有Cl- 和CrO42- 的溶液，其浓度均为0.01mol/L，向该溶液中逐滴加入0.01mol/L的AgNO3溶液时，首先产生沉淀的阴离子是      (已知:Ksp(AgCl)=1.56×10-10，Ksp(Ag2CrO4)=9.0×10-12)

（5）合成塔中失活的铬锌触媒可用于制备锌锰电池。在碱性条件下，该电池的总反应为：Zn(s) ＋2MnO2(s) ＋H2O(l) = Zn(OH)2(s) ＋Mn2O3(s) ，该电池正极的电极反应式是                   。若用电池电解(惰性电极)足量的Mg(NO3)2和NaCl的混合溶液，电解过程中阴极的现象是                            。
