9.【答案】A【解析】四种短周期主族元素原子序数依次增大且占据三个周期，故W是H元素：元素X的非金属性在元素周期表中最强，故X是F元素：元素W和Y同主族，故Y是a元素：Z的氧化物可制作光导纤维，故乙是Si元素.NaH是离子化合物，A项正确；Si02是酸性氧化物，B项错误：元素的非金属性越强，氢化物的稳定性越强，故氢化物的稳定性：F>Si,C项错误；F元素无正价，D项错误。10.【答案】D【解析】过程①粗盐提纯的过程Na,CO3溶液加入顺序要在BC,溶液之后，目的是除去Ca2+和过量的Ca2+,A项错误：过程②海水淡化中蒸馏法成本较高，B项错误：过程③中包含制取MgCl,溶液、无水MgCl2及电解熔融MgCl2等步骤，C项错误；过程④中SO2水溶液吸收Br2后生成HS04和B,溶液的酸性增强、pH减小，D项正确.11.【答案】C【解祈】稀HNO3溶液和铜反应生成无色的NO气体，在试管口再与氧气反应转变为红棕色NO,A项错误：向淀粉溶液中先加入稀硫酸并加热，再加入碘水溶液变蓝也可能是淀粉部分水解，B项错误：氯水和I反应生成1)和C1,说明还原性：>C1,四氯化碳萃取生成的)且密度大于水，下层溶液显紫色，C项正确；向碳酸钠溶液中滴加足量盐酸，产生无色无味的气体，说明酸性：HCl>H,CO3,并不能证明非金属性：CI>C,D项错误.12.【答案】D【解析】由示意图可知，②-~③是化学键断裂的吸热过程，A项正确；③→④是N原子和H原子形成NH中N一H极性键的过程，B项正确；合成氨反应是放热反应，故反应物旧键断裂吸收的能量小于生成物新键形成释放的能量，C项正确；其他条件相同，使用催化剂不会减少合成氨反应放出的热量，D项错误.13.【答案】D【解析】装置甲和乙中锌片均发生失电子的氧化反应，A项正确：装置甲溶液中的向正极铜片移动，B项正确；装置甲和乙中发生的总反应都是Zn+H,S0,一ZnSO,+H,个，均会导致溶液的质量增加，C项正确；装置甲形成了原电池，反应速率更快，D项错误.14.【答案】c【解析】根据2n三种物质的物质的量变化可知，该该反应的化学方程式为2A+B、三2C,A项正确；保持容器容积不变，充入氢气，反应物和生成物的浓度不变，反应速率不变，B项正确：恒温、恒容条件下，气体的压强之比等于物质的量之比，故衡时容器内气体的压强与反应前的比值为8：9，C项错误：气体的总质量守恒，当容器内混合气体的均摩尔质量不变时说明气体总的物质的量保持恒定，反应达到衡状态，D项正确.二、非选择题：本题共4题，共58分.15.（14分，每空2分)【答案】(1)A1第二周期，第VIA族(2)F->Na*>H+
