兴衡中学校办工厂生产氢氧化钠的反应原理为:Ca(0H)2+Na2CO3═CaCO3↓+2NaOH,其产品中含有少量的碳酸钠.在产品出厂前都要检验氢氧化钠的纯度,看是否达到生产要求.在某次检验中,技术员取样l00g,加入足量水溶解后,滴加氯化钡(BaCl2)溶液21.6g时,恰好反应完全,经过滤、洗涤、干燥后得到碳酸钡(BaCO3)固体3.94g.

试求:

(1)该产品中氢氧化钠的纯度(假设产品中的杂质只有碳酸钠)(最后结果准确到0.01%).

(2)反应前氯化钡溶液中溶质的质量分数.

In the doorway of my home, I looked closely at my 23-year-old son, Daniel. In a few hours he would be flying to France to   36  a different life. It was a transitional(过渡的)time in Daniel's life. I wanted to    37  him some words of significance. But nothing came from my lips, and this was not the    38  time I had let such moments pass.
When Daniel was five, I took him to the bus stop on his first day of kindergarten. He asked, “What is it going to be like, Dad? Can I do it?” Then he walked   39  the steps of the bus and disappeared inside. The bus drove away and I said nothing. A decade later, a similar   40 played itself out. I drove him to college. As I started to leave, I tried to think of something to say to give him    41 and confidence as he started this new stage of life. Again, words 42  me.
Now, as I stood before him, I thought of those 43  opportunities. How many times have I let such moments   44 ? I don't find a quiet moment to tell him what they have  45  to me. Or what he might   46  to face in the years ahead. Maybe I thought it was not necessary to say anything.
What does it matter in the course of a lifetime if a father never tells a son what he really thinks of him?    47  as I stood before Daniel, I knew that it did matter. My father and I loved each other. Yet, I always   48  never hearing him put his   49   into words. Now I could feel my palms sweat and my throat tighten. Why is it so   50  to tell a son something from the heart?
My mouth turned dry, and I knew I would be able to get out only a few words clearly. “Daniel,” I said, “If I could have picked, I would have picked you.” That's all I could say. He hugged me. For a moment, the world    51 , and there were just Daniel and me. He was saying something, but tears misted my eyes, and I couldn't understand what he was saying. All I was    52  of was the stubble(短须)on his chin as his face pressed   53  mine. What I had said to Daniel was   54 . It was nothing. And yet, it was  55 .
