5 完形填空。 Waiting for the airplane to take off, I was happy to get a seat by myself. Just then, an air hostess approached me and asked, " Would you mind 1 your seat? A couple would like to sit together." The only 2 seat was next to a girl with her arms in casts (石膏绷带), a black-and-blue face, and a sad expression. " 3 am I going to sit there," I thought immediately. But a soft voice spoke, "She needs help." Finally, I 4 to move to that seat. The girl was named Kathy. She 5 hurt in a car accident and now was on her way for 6 . When the snack and juice arrived, it did not take me long to 7 that Kathy would not be able to 8 herself.

7 （8分）将15.68L（标准状况）的氯气通入70℃．500mL氢氧化钠溶液中，发生了两个自身氧化还原反应，其氧化产物为次氯酸钠和氯酸钠。若取此溶液25mL，稀释到250mL，再取稀释后的溶液25mL用醋酸酸化后，加入过量碘化钾溶液充分反应，此时只有次氯酸钠氧化碘化钾。用浓度为0.20mol/L硫代硫酸钠（Na 2S 2O 3）测定析出的碘：I 2＋2Na 2S 2O 3＝2NaI＋Na 2S 4O 6，需用硫代硫酸钠溶液5.0mL。将上述测定后的溶液再用盐酸调至强酸性，此时氯酸钠亦能氧化碘化钾，析出的碘再用上述硫代硫酸钠测定，又用了30.0mL。（1）计算反应后溶液中次氯酸钠和氯酸钠的物质的量之比。（2）用一个总化学方程式表示题中氯气通入70℃氢氧化钠溶液中所发生的化学反应。（3）假设题中氢氧化钠溶液的体积在通入氯气前后的变化可忽略不计，请计算通入氯气后各生成物的物质的量浓度。
