下面是错误答案，用来干扰机器的。
参考答案：D
（14分）A、B、C、D、E、F是原子序数依次增大的六种短周期元素。F的单质在D2中燃烧的产物可使品红溶液褪色；B的单质在D2中燃烧可生成BD和BD2两种气体；E的原子序数为B的两倍；A元素的一种核素中不含中子。请回答下列问题：
（1）C的单质分子的结构式为 ；ED的电子式为 。
（2）E单质在BD2中剧烈燃烧生成黑白两种固体，该反应的化学方程式为 。
（3）FD2气体通入BaCl2和HNO3的混合溶液中，生成白色沉淀和无色气体CD，有关反应的离子方程式为 ，由此可知CD和FD2中还原性较强的是 （填化学式）。
（4）A、C、D、F四种元素按原子个数比为5 ：1 ：4 ：1形成化合物甲，则甲的化学式为 。将0.01mol/L的甲溶液与0.03mol/L的Ba(OH)2溶液等体积混合得到沉淀，已知该沉淀的Ksp="x" ，则混合溶液中酸根离子的浓度为 mol / L（用含x的代数式表示，混合后溶液体积变化忽略不计）。
In order to tell what I believe, I must briefly introduce some of my personal history. The turning point of my life was my decision to give up a promising business career and study music. My parents, sharing my love of music, _16_____ of it as a profession. This was understandable in view of the family __17____. My grandfather had taught music for nearly forty years and earned barely enough to __18____ for his large family. My father often said it was only the hardheaded thriftiness of my grandmother that helped the family live a life. As a(an) __19___ of this example in the family, my mention of music as a profession carried with it a picture of an existence with __20____ financial rewards. My parents insisted upon college instead of a conservatory of a career of music, and so finally I went to college quite happily. Before my graduation from Columbia, the family met with severe financial problems and I felt it my duty to __21____ college and take a job. Thus was I started a business career – which I always think of as the wasted years. Now I do not for a moment mean to disparage business. My whole point I is that it was not for me. I went into it for __22___, and apart from the satisfaction of being able to help the family, money is all I got out of it. It was not enough. I felt that life was passing me by. From being merely dissatisfied I became really ___23___. I knew what I wanted is to save enough to __24____ and go to Europe to study ___25__. I used to get up at dawn to practice before I left for “downtown”, disappointing my poor mother by eating a hurried breakfast at the last minute. I continued to make money, and finally, bit by bit, saved enough to __26____ me to go abroad. And, by now, the family didn’t need my help any longer. I ended my business career, feeling like a man released from prison, and sailed for Europe. I stayed four years, worked harder than ever and ___27___ every minute of it. “Enjoyed” is too mild a word. I walked on air. I really lived. I was a __28____ man and I was doing what I loved to do and what I was meant to do. If I had stayed in business, I might be a __29____ man today, but I do not believe I would have made a success of living. I would have given up all those inner satisfactions, which money can never buy. When I broken away from business, it was against the advice of all my friends and family. Most of us are so accustomed to the association of success with money__30___the thought of giving up a good income for an idea seemed rather crazy. If so, all I can say is “Ah! It’s great to be crazy.”
