卤素间形成的化合物如“IF5、BrCl、IBr”等称为卤素互化物,化学性质与卤素单质类似,则下列关于卤素互化物的性质的描述及发生的相关反应不正确的是( ) 

A.IF5 + 3H2O = HIO3 +5HF

B.3IBr +2Fe = FeI3 + FeBr3

C.BrCl的氧化性强于I2

D.IBr可以与NaOH溶液反应生成2种盐

答案

答案:B

题目分析:A.IF5发生水解,生成HIO3和HF,方程式为IF5+3H2O═HIO3+5HF,故A正确;B.由于氧化性Fe3+>I2,IBr与铁反应生成FeI2,故B错误;C.Cl、Br的非金属性比I强,BrCl的氧化性强于I2,介于氯气和溴之间,故C正确;D.IBr可以与NaOH溶液生成NaIO和NaBr,故D正确。故选B.

(19分)阅读下列材料,结合所学知识回答问题。

材料一 我们上层制定的经济政策是同下层脱离的,这一政策没有造成生产力的提高,而这一点在我们的党纲里却被认为是刻不容缓的任务。……向纯社会主义形式和纯社会主义分配直接过渡,是我们力所不及的。如果我们不能实行退却,即把任务限制在较容易完成的范围内,那我们就有灭亡的危险。

——《列宁全集》

材料二  1920年11月,苏俄人民委员会发布租让法令,允许外国资本家在苏俄经营租让企业或同苏维埃国家组织合营股份公司。列宁强调要通过租让制发展苏俄经济改善工人生活,同时学习资本主义国家的先进技术和生产管理方法。

——馀天新、许平、王红生《世界通史》现代卷

材料三 要建立起充满生机和活力的……经济体制……必须大胆吸收和借鉴人类社会创造的一切文明成果,吸收和借鉴当今世界各国包括资本主义发达国家的一切反映现代社会化生产规律的先进经营方式和管理方法……一切要以是否有利于发展社会主义的生产力、有利于增强社会主义国家的综合国力、有利于提高人民生活水平这“三个有利于”为根本判断标准。

     Maybe you have ever seen a cross. A cross can be a piece of jewelry or an image in a painting. But do

you know the cross is a very popular symbol for Christmas?

     It came from the story of Jesus' death on the cross two thousand years ago in Jerusalem. Jesus was

Jewish,and at that time Jewish people were under Roman rule. Jesus was badly punished because he declared

to be the Son of God and the King of Jews. Surely, the Son of God could have saved himself from the death!

But the Bible says that Jesus had a reason to die that day. It was in God's purpose that it would happen.

     Christians call the day that Jesus died "Good Friday". At first, it is hard to understand how a terrible day

could ever be called good. Well, the story does not end there. Jesus died and he was buried. But three days

later, Jesus was alive, and the whole world was changed.

     Today, Christians everywhere remember this important time. They celebrate Easter. Easter is the day that

Jesus rose from the dead. After his death on the cross,Jesus' body was placed in a tomb. On the third day

from then, God raised him from the dead. Jesus stayed on earth physically for several weeks. Many people

saw him. Easter is the happiest time of year for Christians because they believe that Jesus had victory over

death and evil and that now he lives with God the Father in heaven. But before celebrating Easter, Good Friday

should be remembered. Jesus died a horrible and painful death. He suffered, though he did noting wrong.

Christian believe that Jesus was God's substitute (代表) for humans, because humans all do wrong. He died

because of humans and he died for humans. 

     Christians often wear crossed around their necks of hang them in their homes because they believe it is a
