A、Z、R、D、E、F、G是七种原子序数依次增大且不大于20的元素,其中有两种非金属元素位于同一土族。己知A、Z、D均能与R形成原子(或离子)个数不同的儿种常见化合物。请回答下列有关问题。

(1)若X、Y是D、F形成的最高价氧化物对应的水化物,浓度均为0.1mol/L的X、Y溶液的pH之和为14,则X、Y的晶体熔点相对高低为(写化学式)             ,导致这种差异存在的原因是                                在相同温度下,相等物质的量浓度的X、Y各自的溶液中,由水电离出的c(H+)的相对大小关系为   

(2)A与Z、E均可形成正四面体构型的气态分子Q、P,又知P的燃烧热为1430kJ/mol.则其燃烧的热化学方程式             

(3)R与D、F间;R与F、G间均可形成多种化合物,其中有两种是目前广泛使用的具有消毒杀菌能力的化合物。则相同物质的量浓度的这两种物质的溶液,消毒杀菌能力较强的物质的化学式为                         ,另一种物质的溶液中,各离子浓度由大到小的顺序为                       

(4)上述七种元素间能形成多种常见二元化合物,其中Z与G形成的一种化合物存在两类化学键的物质溶于HC1溶液的化学反应方程式为                    ,ZR2的电子式是        ,该分子的空间构型为     化合物ZRF2的结构式为____

(5)R能形成多种单质,如R2、R3,研究表明,新近制得的一种组成为R4的分子中,每个R原子均与另外两个R原子各形成一个键,则1molR4中共用电子对数为____NA,列有关R4的说法中正确的是

Recently, one of my best friends, whom I’ve shared just about everything with since the first day of kindergarten, spent the weekend with me.Since I moved to a new town several years ago, we’ve both always looked forward to the few times a year when we can see each other.

Over the weekend, we spent hours and hours, staying up late into the night, talking about the people she was hanging around with.She started telling me stories about her new boyfriend, about how he experimented with drugs and was into other self-destructive behavior.I was blown away! She told me how she had been lying to her parents about where she was going and even stealing out to see this guy because they didn’t want her around him.No matter how hard I tried to tell her that she deserved better, she didn’t believe me.Her self-respect seemed to have disappeared.

I tried to convince her that she was ruining her future and heading for big trouble.I felt like I was getting nowhere.I just couldn’t believe that she really thought it was acceptable to hang with a bunch of losers, especially her boyfriend.

By the time she left, I was really worried about her and exhausted by the experience.It had been so frustrating, I had come close to telling her several times during the weekend that maybe we had just grown too far apart to continue our friendship,but I didn’t.I put the power of friendship to the final test.We’d been friends for far too long.I had to hope that she valued me enough to know that I was trying to save her from hurting herself.I wanted to believe that our friendship could conquer anything.

A few days later, she called to say that she had thought long and hard about our conversation, and then she told me that she had broken up with her boyfriend.I just listened on the other end of the phone with tears of joy running down my face.It was one of the truly rewarding moments in my life.Never had I been so proud of a friend.
