同类题2

高锰酸钾是一种盐,可溶于水,溶液显紫红色.课本上有一个“估算高锰酸根离子的大小”的实验,某同学按课本实验步骤操作如下:
①取一小粒高锰酸钾晶体(实验室用的高锰酸钾晶体粒径大约为1﹣﹣3毫米),用毫米刻度尺测量并估算其体积为Vmm3;
②将该高锰酸钾晶体溶解在有10毫升水的试管1中;
③从试管1中取出1毫升溶液,将其加人有9毫升水的试管2中(第一次稀释);
④从试管2中取出1毫升溶液,将其加人有9毫升水的试管3中;
⑤以上述方法继续稀释高锰酸钾溶液,到刚看不出高锰酸钾溶液的紫红色为止时,共稀释10次;
特别提示:已知在第9次稀释时,还能看出溶液呈淡紫红色.此时10毫升溶液中有1000个高锰酸根离子.该数据可作为本实验的估算比较标准.
请回答以下问题:
(1)在取1毫升高锰酸钾溶液时,若俯视量筒读数,则所取溶液体积____1毫升(选填“大于”、“等于”或“小于”).
(2)下列课本中的哪一个实验,与本实验方法相似的是____.
   A.验证植物光合作用产生氧气    B.测定空气中氧气的含量    C.用pH试纸测定溶液的酸碱度   D.探究物体所受浮力与排开水的关系
(3)要提高该实验估算的准确度,下列哪两种改进方法一定正确的是____.
  A.在一支试管中加人蒸馏水作为无色标准,与稀释后的溶液加以比对
  B.每次稀释时都从试管中取2毫升溶液,将其加人有18毫升水的试管中
  C.将高锰酸钾晶体放人盛有蒸馏水的量筒中,根据量筒中液面变化,测量其体积
  D.用托盘天平称量一小粒高锰酸钾晶体的质量,根据其密度计算出体积
(4)按该同学实验方法估算高锰酸根离子的大小约是____ mm3;(用式子表示)

    Both of my parents worked full-time when I was a little girl, so my grandmother would stay at our house during the day. We would watch game shows in the living room. Our favorite was The Price is Right. We would call out our answers along with the contestants.

    When I got older and started going to school, we couldn't watch our game shows regularly. That was okay with me, though, because the one thing I liked better than watching game shows with my grandmother was helping her bake. Watching her in the kitchen was amazing: she never seemed to need the recipes but everything she made tasted delicious.

    At first I would just sit in the kitchen and watch, even though I didn't understand what she was doing. As I got older, she let me help with the easy parts, such as measuring the sugar. The day she let me separate the eggs,I felt like I had found complete pleasure.

    At last, my parents decided that I could take care of myself,and my grandmother stopped coming over every day. The love of baking, however, stayed with me. I started baking by myself, and even if the cookies ended up burnt sometimes, more often they turned out pretty well. I tried out new recipes, and whenever I got to a thorny part, I would call my grandmother for advice. Sometimes I would call her just to talk, too. I felt like I could talk to her about anything.

    My grandmother passed away ten years ago, but I still think of her every day. Last week, I found a recipe book she made for me. It included her recipes for brownies, cookies, and my favorite, lemon pie. As I looked through the pages, I thought I could hear her voice. She was the one who taught me not just about baking, but about life.
