高锰酸钾前系数为2，转移电子10个，则草酸前系数为5，则二氧化碳前系数为10，硫酸锰前系数为2，再根据原子守恒，进行配平，化学方程式为2KMnO4+5H2C,O4+3H2S0,=K,SO,+2MnS0+10C02个+8H,0.【小问2详解】配制KMO4标准溶液，步骤为计算、量取、稀释、冷却、移液、洗涤、定容、摇匀等，故配制溶液时一定需要的为量筒、烧杯、玻璃棒、容量瓶、胶头滴管，一定不需要的是圆底烧瓶和分液漏斗，答案选AC.【小问3详解】定容时仰视刻度线，导致溶液的体积偏大，所得溶液的浓度小于0.1000mol/L,若高锰酸钾溶液在移液至容量瓶中时洒落少许，则溶质减少，溶液浓度小于0.1000mol/L。【小问4详解】20mL0.1mol/L的高锰酸钾溶液中高锰酸钾的物质的量为2×103mol,根据方程式可知，草酸的物质的量为5×103mol,根据草酸根离子守恒，可得Ca2+的物质的量为5×103mol,则Ca2+的质量为0.2g,其质量浓度为0.2g÷0.1L=2g/L。【小问5详解】CaC,O~B设B的相对分子质量为x,则128x,解得x=100,CaC204相对分子质量为128，6.4g5gB与CaC2O4相对分子质量相差28，则B为CaC3,所以固体A到B的化学方程式为CaC204=CaC03+C0↑。18.我国规定，食盐中加入KIO3。某厂生产碘酸钾(KIO3)的工艺流程如图：I2.KClO,.H3O硝酸加热反应器酸化冷却，结晶KH(IO)2过滤一系列操作碘酸钾调pH=10溶解试剂A请回答下列问题：(1)试剂A是；流程图中“一系列操作”包括蒸发浓缩、降温结晶、过滤、洗涤、干燥。其中，“洗涤剂”是75%的酒精，而不用蒸馏水，其主要原因是(2)工业上，还可用电解法制取KIO3。以石墨和不锈钢为电极材料，电解KI溶液。化学方程式为KI+3H,0通电KIO+3H↑.在该反应中，氧化产物是(3)常用KI淀粉试纸检验碘盐，其操作是：取少量样品溶于蒸馏水，加几滴食醋，用KI第14页/共19页

20.电突触（如右图所示）是与化学性突触相对应的另一类突触。它的信息传递是通过贯通细胞间隙孔道（缝隙连接）来实现的，不需要神经递质来介导，而是电信号直接传递。结合以上信息，下列相关说法错误的是A.信息传递通常具有双向性B.传递速度快，几乎没有突触延搁动作电位C.可以保证相邻近的细胞同步活动缝隙连接D.更适应高级神经系统的活动21.学习和记忆是脑的高级功能，记忆力也是我们学习能力中一种十分重要的能力。下列相关说法错误的是动作电位A.学习和记忆需要多个脑区和神经通路参与B.短期记忆形成快但是不稳定，且记忆容量有限C.第二级记忆储存的信息不易被之后的信息干扰而遗忘D.经常运用已学过的概念去解释相关的现象，概念就不容易遗忘22.神经纤维的中部受到适宜刺激后产生的神经冲动在神经纤维上传导的某一时刻，神经纤维上各点的膜电位情况如下图所示，其中正确的是刺激刺激AB刺激刺激C23.成年人排尿时，神经冲动的传导途径是A.大脑皮层→脑干下行传导束→脊髓下行传导束→副交感神经→膀胱B.大脑皮层→脑干下行传导束→脊髓下行传导束交感神经膀胱C.大脑皮层→脑干下行传导束→脊髓下行传导束→排尿中枢→副交感神经→膀胱D.膀胱内压力感受器→内脏感觉神经→排尿中枢→副交感神经→膀胱24.科学家在实验中观察到：阻断实验动物垂体与下丘脑之间的血液联系，可导致其生殖器官萎缩；若恢复垂体与下丘脑之间正常的血液联系，生殖器官的功能也恢复正常。下列说法不合理的是A.该实验表明垂体的活动受下丘脑控制B.该实验表明动物生殖器官的发育受垂体的直接控制C.阻断垂体与下丘脑之间的血液联系，依据了“减法原理”D.手术前、后的两组数据可以用统计学方法处理，求出差异25.人体呼吸运动是在各级呼吸中枢相互配合下进行的，呼吸中枢分布在大脑皮层、脑干和脊髓等部位。体液中的02、C02和H浓度变化通过刺激化学感受器调节呼吸运动。有关叙述错误的是A.人体细胞能从血液、组织液和淋巴液等细胞外液获取O2B.人屏住呼吸一段时间后，血液中的C02含量增大，pH变小C.睡眠时不需要有意识地控制呼吸运动，人体仍进行有节律性的呼吸运动D.当吸入气体中C02浓度过大时，可能会出现呼吸困难、昏迷等现象高二年级生物学科试卷共9页第4页
