1 （8分）氯气及氯的化合物有着广泛的应用（1）已知可逆反应Cl 2+H 2O HCl+HClO，向氯水中加入NaHCO 3固体后，溶液中HClO的浓度（填增大、减小、不变），原因是：。（2）我国卫生部已明确提出：逐步用二氧化氯替代氯气进行饮用水的消毒。 ①用ClO 2处理过的饮用水（pH为5.5～6.5）常含有一定量对人体不利的亚氯酸根离子(ClO 2 －)。卫生部规定，饮用水中ClO 2 －的含量应不超过0.2mg·L － 1。当pH≤2.0时， ClO 2 －能被I －还原成Cl －。请写出反应的离子方程式。 ②用ClO 2处理过的自来水中会残留ClO 2 ，可用FeCl 2将ClO 2还原为Cl -，该反应的氧化产物是（填化学式）。现用V L(已换算为标准状况)ClO 2处理一定量自来水，再加入a mol FeCl 2可将残留的ClO 2恰好除去。则该自来水中残留ClO 2的物质的量为 mol。

8 阅读理解。 Have you ever thought, "I wish I could take a year off and just travel around the world"? Well, three lucky American teenagers were able to do just that. The teens-two males and one female-got an all-expenses paid, yearlong hike to five continents. This trip didn"t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn"t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters (遇到) with some of nature"s most dangerous animals and environments. Jamie, Arsen, and Tyler were among hundreds of high school kids nominated (提名) by their science teachers to take this trip. Earthwatch Institute sponsored (赞助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects. The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya"s Great Rift alley, and tracking giant sea turtles in Costa Rica. As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person"s actions. They realized that each of them can make a difference. 1. These teenagers went on the journey around the world _____. A. to experience the most serious environmental problems on the earth B. to bring the kindness of America to the other parts of the world C. to go on sightseeing around the world D. to call on more teenagers to join Earthwatch Institute 2. What"s true about their journey? A. They had to pay for their journey on their own expense. B. They often had to move from one hotel to another. C. They had to take great pains to collect environmental information. D. They received a warm welcome every time they arrived at a new place. 3. It can be inferred that Earthwatch Institute could be ____. A. an international university that takes in students from all over the world B. a TV station that makes programmes on the beautiful scenery of the earth C. a travel agency that organizes adventure trips specially for school children D. an organization that brings science to life for people concerned about earth"s environment 4. What did they these teenagers learn from the journey? A. It was high time that people protected the environment. B. Long journey was not suitable for school children. C. It should take the whole world to help the children. D. Environmental problems can be solved if school children take part.
