B．Valuing human relationships.
C．Possessing a good memory.
二、阅读理解
Temples have existed for thousands of years. They are the proof of cultures and civilization that existed many years ago.
Gobekli Tepe, Turkey
Located on a hilltop in southwestern Turkey where it snows a lot in winter, the Gobekli Tepe is considered the world’s oldest temple. It is nearly 11000 years old. There are carvings on the rock statues, mainly of lions, foxes, snakes, cranes and wild ducks, as well as scenes of people hunting. Because heavy snow makes it hard to get to the top of the hill, visitors are not recommended to go there in winters.
White Temple, Thailand

6、重庆市七校联盟2025-2026学年高二上学期七校联考 答案


C．反应过程中“”分成“”和“”
D．该研究有利于实现“碳中和”目标
【答案】A
【知识点】催化剂的特点与催化作用；微粒观点及模型图的应用；根据化学反应方程式的计算；二氧化碳对环境的影响
【解析】【解答】A、消耗CO2与生成CH3OH的质量比 = (44×1)：(32×1) = 11：8，不是11：16，错误；
B、催化剂能加快反应，CO2、H2得与催化剂接触才反应，正确；
C、反应中CO2分子会分成C、O原子（微观拆分 ），正确；


【详解】A．由题意知，电对的标准电极电势(φθ)越高，其电对中氧化剂的氧化性越强，根据表中数据，酸性介质中φθ(HClO/Cl-)=1.49V＞φθ(Cl2/Cl-)=1.36V，所以酸性介质中氧化性Cl(0价)＜Cl(+1价)，A正确；
B．酸性条件下，φθ(HClO/Cl-)=1.49V＞φθ(Fe3+/Fe2+)=0.77V，碱性条件下，φθ(ClO-/Cl-)=0.81V＞φθ[Fe(OH)3/Fe(OH)2]=-0.56V，故在酸性或碱性条件下，氧化性Cl(+1价)＞Fe(+3)，因此酸性、碱性条件下，Cl(+1价)均可以氧化Fe(+2价)，B正确；
C．酸性条件下，φθ(Co3+/Co2+)=1.84V＞φθ(Cl2/Cl-)=1.36V，所以Co3O4可以将Cl-氧化为Cl2，反应的方程式为：Co3O4+8H++2 Cl-=3 Co2++Cl2↑+4H2O，C错误；
D．依据题意，在碱性条件下，φθ(ClO-/Cl-)=0.81V＞φθ[Co(OH)3/Co(OH)2]=0.17V，故碱性条件下氧化性ClO-＞Co(OH)3，若将钴(+2价)氧化为钴(+3价)需要在碱性条件下加入次氯酸钠才可发生反应，D正确；
故答案为：C。
15. 84消毒液是一种以NaClO为主的高效消毒剂。为探究NaClO与KI溶液的反应机理，进行如下实验。下列分析错误的是
实验 滴管 烧杯 现象
