我国化工专家侯德榜先生发明的“侯氏制碱法”的基本原理是:在浓氨水中通入足量的二氧化碳生成一种盐,然后在此溶液中加入细小的食盐粉末;由于碳酸氢钠在该状态下溶解度很小,呈晶体析出,同时由于碳酸氢钠不稳定,加热后生成纯碱.水和二氧化碳;再向析出碳酸氢钠后的氯化铵溶液中加入食盐,使其中的氯化铵单独结晶出来,氯化钠则可循环使用。根据以上叙述简要回答问题:

(1)用上述方法进行实验时,所用的起始原料____________________。(写出它们的化学式,下同)。

Traveling can be a fun way to gain life experiences, especially during Spring Break — a week-long school vacation in the United States. But what if you're a student and don't have enough money for a trip? Don't worry. Here are some useful suggestions.

●Save: This probably is the most important preparation for traveling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

●Plan ahead: Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.

●Do your homework: No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

●Plan sensibly: Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

●Travel in groups: Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.

●Work as you go: Need more money to support your trip? Look for work in the places you visit.

●Go off the beaten path: Tourist sites may be expensive. You may want to rethink your trip and go to a less-known area. Smaller towns can have many interesting activities and sights.

●Pack necessary things: The most important things to take are not always clothes.

Remember medicine in case you get sick, and snacks in case you cannot find a cheap restaurant.

●Use the Internet: The net can help to save money. Some useful websites include www. travelcity. corn, www. bargainslowestfare. corn and www. economictravelcity. com.

By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.
