2014年安徽高考理综化学试题解析 第Ⅰ卷 的资源化利用是解决温室效应的重要途径，以下是在一定条件下用NH3捕获CO2生成重要化工产品三聚氰酸的反应： NH3+CO2 +H2O 下列有关三聚氰酸的说法正确的是 A．分子式为C3H6N3O3 B．分子中既含极性键，又含非极性键 C．属于共价化合物 D．生成该物质的上述反应为中和反应 【答案】C 【解析】三聚氰酸分子式为C3H3N3O3，分子中只含极性键(碳氮极性键、碳氧极性键和氧氢极性键)。氰酸的结构为HO—C≡N，3个氰酸分子发生加成生成三聚氰酸。本题是用NH3捕获CO2在一定条件下生成三聚氰酸，其过程是：NH3先与CO2发生加成反应生成中间产物氨基甲酸H2N—COOH，3个H2N—COOH失去3个水分子生成三聚氰酸。 8.下列有关Fe2(SO4)3溶液的叙述正确的是 A．该溶液中，K+、Fe2+、C6H5OH、Br—可以大量共存 B．和KI溶液反应的离子方程式： Fe3+ +2I—== Fe2+ +I2 C．和Ba(OH)2溶液反应的离子方程式： Fe3+ +SO42—+Ba2+ +3OH—== Fe(OH)3↓+BaSO4↓ D．1 mol/L该溶液和足量的Zn充分反应，生成 gFe 【答案】D 【解析】A选项：Fe3+与C6H5OH反应：Fe3++6C6H5OH==[Fe(OC6H5)6]3—+6H+ B选项：正确的离子方程式为2Fe3+ +2I—== 2Fe2+ +I2 C选项：正确的离子方程式为2Fe3+ +3SO42—+3Ba2+ +6OH—== 2Fe(OH)3↓+3BaSO4↓ 9.为实现实验目的，依据下表提供的主要仪器，所用试剂合理的是 选项实验目的主要仪器试剂 A分离Br2和CCl4混合物分液漏斗、烧杯Br2和CCl4混合物、蒸馏水 B鉴别葡萄糖和蔗糖试管、烧杯、酒精灯葡萄糖溶液、蔗糖溶液、银氨溶液C实验室制取H2试管、带导管的橡皮塞锌粒、稀HNO3 D测定NaOH溶液浓度滴定管、锥形瓶、烧杯NaOH溶液、 mol/L盐酸 【解析】A选项：Br2和CCl4是两种互溶的液体，Br2和CCl4混合物是溶液，不能通过分液的方法分离。 B选项：葡萄糖是还原性糖(分子中含—CHO)，蔗糖是非还原性糖(分子中不含—CHO)。 C选项：实验室制取H2的试剂通常是用锌粒和稀盐酸或稀硫酸，不是稀硝酸。锌与稀硝酸反应反应通常不能得到H2，而是低价氮的化合物或氮单质。 D选项：缺少酸碱指示剂。 10.臭氧是理想的烟气脱硝试剂，其反应为：2NO2(g)+O3(g) N2O5(g)+O2(g)，若反应在恒容密闭容器中进行，下列由该反应相关图像作出的判断准确的是 A B C D
