NA表示阿伏伽德罗常数的值。下列说法正确的是（） A标准状况下，和CH4的混合气体中所含电子数为2NA B/LCH3COOH溶液中含有的离子和分子总数是 C等物质的量的干冰和葡萄糖中所含碳原子数之比为1:6，氧原子数之比为1:3 D晶体中阴、阳离子总数为 答案：C 解析： A:每个NH3和CH4分子中均含有10个电子，所以标准状况下，和CH4的

2、混合气 体即为1mol,所含电子数为NA。所以错误。 B: CH3COOH溶液中除了有醋酸分子外还含有水分子，所以/LCH3COOH溶液中含有的离子和分子总数要远远大于。所以错误。 C: 干冰即二氧化碳分子式为CO2,葡萄糖分子式为C6H12O6，所以等物质的量的干冰和葡萄糖中所含碳原子数之比为1:6，氧原子数之比为1:3。所以C正确。 D: Na2O2晶体中阴、阳离子分别为Na+和O22-(过氧根离子)，所以晶体中阴、阳离子总数为。所以D错误。 8.汽车在剧烈碰撞时，安全气囊中发生的反应为：10NaN3+2KNO3=K2O+5Na2O+16N2， 下列关于该反应的说法正确的是（） A N2中

3、键与键个数比为1:2 B反应物和生成物中只有氮气属于非电解质 C该反应每转移1mol电子，生成氮气 DNaN3是只含有离子键的离子化合物 答案A 解析： A氮气分子中存在氮氮三键，不论氮气多少,氮分子中键与键个数比为1:2,所以A 正确； B中氮气属于单质，所以既不是电解质也不是非电解质；所以错误。 C中没有标准状况；所以错误。 D中钠和氮之间是离子键，氮和氮之间是共价键。所以错误。 9X、Y、Z、W、Q是原子序数依次增大的五种短周期主族元素。其中只有Z是金属，W的单质是黄色固体，X、Y、W在周期表中的相对位置关系如图。下列说法正确的是（） A五种元素中，原子半径最大的是W BY的简单阴离子比

4、W的简单阴离子还原性强 CY与Z形成的化合物都可以和盐酸反应 DZ与Q形成的化合物水溶液一定显酸性 答案：C 解析： 由题意可知，X、Y、Z、W、Q分别为C、O、Na或Mg或Al、S、Cl。 A：Z为第三周期元素，电子层数最多，故半径最大。故A错误。 B:Y的单质比W的单子氧化性强，所以Y的简单阴离子比W的简单阴离子还原性弱。故B错误。 C: Y、Z形成的化合物有Na2O和Na2O2，二者均可以和盐酸反应。故C正确。 D: Z、Q形成的化合物为Na Cl，溶液呈中性。故D错误。 10、下列实验装置图能实现对应的实验目的的是 图1 图2图3 图4 A利用图1除去Cl2中的HCl B利用图2由45

5、白酒制无水乙醇 C利用图3检验产物中含有乙烯 D图4是研究温度对NO2和N2O4平衡的影响 答案：.D 解析: A:除去Cl2中的HCl用饱和的NaCl溶液，A选项错误。 B:白酒通过蒸馏只能得到大约96%的乙醇溶液，不能制得无水乙醇，B选项错误。 C:溴乙烷与NaOH乙醇加热制得的乙烯混有乙醇，乙醇也可使酸性KMnO4溶液褪色，必须通过水洗后，再用酸性KMnO4溶液检验，C选项错误。 D项，反应NO2?N2O4H0，若升高温度平衡逆向移动混合气体颜色加深，若降低温度平衡正向移动，混合气体颜色变浅，正确。 11.某烃的衍生物 A ，分子式为 C 6H12O2。实验表明A跟氢氧化钠溶液共热生成B

6、和C， B 跟盐酸反应生成有机物D，C在铜催化和加热条件下氧化为E，D和E属于不同类别的物质， 其中D不能发生银镜反应而E能发生银镜反应。由此判断A的可能结构有（ ） A6种B7种 C8种D9种 答案：D 解析：由题可知A为酯，D为酸C为醇E为醛。由于D不能发生银镜反应所以不是甲酸，若D是乙酸则E为丁醛，丁醛有2种，此时A有2种；若D是丙酸则E为丙醛，丙醛有1种，此时A有1种；若D是丁酸则E为乙醛，丁酸有2种，乙醛有1种，此时A有2种；若D为戊酸则E为甲醛，戊酸有4种，甲醛有1种，所以此时A有4种。所以符合条件的A共有2+1+2+4=9. 12.下列图示与对应的叙述相符的是（） A图1表示反应

7、2NO(g)+2CO(g) B图2中表示反应2A(g) + B(g)N2(g)+2CO2(g)平衡常数K 随NO物质的量的变化 2C(g) H 0的平衡常数K随温度的变化 3C(g)+D(s)的影响，乙的压强比甲的压强小 C图3表示压强对可逆反应2A(g)+2B(g) D据图4，若除去CuSO4溶液中的Fe3+可向溶液中加入适量CuO至pH在5-6左右 答案：A 解析： A:平衡常数只和温度有关，故A选项正确； B: H 0,该反应正方向为吸热反应，故正反应K值随温度升高而增大，逆反应K值随温度升高而减小；所以错误。 C：该反应中D物质为固态，正反应为体积减小的反应，增大压强时平衡正向移动，反

8、应物的含量下降，乙压强下反应物百分含量减小所以压强大；故C错误。 D: 若除去CuSO4溶液中的Fe3+,就要求Fe3+沉淀完时Cu2+不沉淀，由图4可知pH在5-6左右Cu2+已有大量沉淀，故D选项错。 HOCH COOH13.酒石酸(HOCOOH) 是一种存在于葡萄等水果中的有机 酸。已知酒石酸在溶液中的微粒浓度和溶液pH的关系如图所示（图中酒石酸用H2T表示）。为测定某果汁中酒石酸的含量（果汁中不含其它酸），小明在实验室中用/L NaOH溶液对果汁（取样20mL）进行滴定。利用传感器技术，测得滴加40mLNaOH溶液时达到滴定终点。下列有关说法正确的是 A果汁中酒石酸的浓度为110-3

9、mol/L B滴加NaOH溶液10mL，溶液中存在c(Na+)= 2c(H2T) +2 c(HT) +2 c(T 2) C滴加NaOH溶液40mL，溶液中存在c(OH-)= 2c(H2T) + c(HT) +c(H+) D滴定过程中生成了NaHT，由于HT水解使溶液呈碱性 答案：C 解析： A:滴加NaOH溶液40mL，达到滴定终点，此时恰好完全反应：2NaOH+H2T=Na2T+2H2O，故酒石酸的起始浓度为 mol/L，A错误； B:滴加NaOH溶液10mL时，NaOH的物质的量为酒石酸的一半，所以溶液中c(Na+) 2c(H2T) +2 c(HT) +2 c(T 2)，B错误； C:滴加

10、NaOH溶液40mL，H2T恰好反应完，此时溶液为Na2T溶液，根据质子守恒可得出c(OH-)= 2c(H2T) + c(HT) +c(H+)，C正确； D:由图像中pH变化可知，NaHT溶液呈酸性。这是由于HT既有电离又有水解，电离使溶液呈酸性，水解使溶液呈碱性，且电离程度比水解程度大，所以最终呈酸性。故D错误。 第2卷 26.（18分） 对溴甲苯是合成农药溴螨酯的重要原料工业用液溴、甲苯与1-丙醇共热合成对溴甲苯和1-溴丙烷，其原子利用率很高实验室模拟的合成流程和相关数据如下： 已知：甲苯与溴在有水存在时能反应 （1）25恒温搅拌至溴的颜色完全褪去时完成甲苯的溴代反应。为提高溴的利用率可采

25、，从26-45各题所给的和D项中选出最佳的选择，并在答 题卡上将该选项涂黑. (A) “Save the whales!” Thats what the picture on Jake Smiths bedroom wall said. Jake liked having a picture that said something important: that showed he cared. He just never expected to get a chance to save a real whale, one right in his own neighbourhood. It

26、was a Saturday morning when the newspaper first reported the whales coming. A group of the animals were swimming close to the beach in Jakes hometown. All the local people rushed out to the beach to see them. They were expecting a beautiful show, better than a movie, but nothing theyd have to do any

27、thing about. Then one whale swam in the direction, directly towards land. It came in with the waves, and when the waves receded. Its huge body on the sand. Suddenly, Jake and his family and all the others were no longer sightseers. They had to become rescuers. A few people ran towards the animal. Th

28、ey pushed and tried to force the whale back into the water, but it was no use. An animal rescue service team soon arrived in a truck with heavy lifting machinery, to help move the animal. Jack and his family couldnt do much on the beach, so they went back to their house and made sandwiches and hot t

29、ea for the rescuers. At least, Jake thought, they could help in some way. Back at the beach, they offered the food to the rescuers and were happy to see that it was needed. It was getting dark. Some people lined up their cars along the beach and shined the headlights on the sand. The rescuers would not give up. After trying many times they were finally able to lift the whale into the water. Everyone cheered when it headed out to sea. It swam out about a mile and then disappeared for a moment under the sea. Then, in what looked like
