下列实验方案合理的是(   )

A.配制银氨溶液:在一定量AgNO3溶液中,逐滴滴加氨水至过量。

B.配制Cu(OH)2悬浊液:在一定量CuSO4溶液中,加入少量NaOH溶液

C.苯中含有少量苯酚,加浓溴水后,过滤除去苯酚

D.鉴别环己烯和甲苯:将溴的四氯化碳溶液分别滴加到少量环己烯和甲苯中

答案

答案:D

配制银氨溶液:往AgNO3溶液滴加稀氨水至生成的沉淀恰好溶解为止,A错误。在一定量CuSO4溶液中,加入足量NaOH溶液,碱过量。苯中含有少量苯酚,加浓溴水后,生成2.4.6—三溴苯酚可以溶于苯,不溶于水,C错误。鉴别环己烯和甲苯,环己烯与溴的四氯化碳溶液加成互溶,甲苯和溴发生萃取分层,D正确。

 If you are in charge of a project, the key to success is getting everyone to want to help you. As a director, I point, I suggest. I gently push the actors in the direction I want them to go. In the 1986 movie, “Nothing in Common”, Jackie Gleason’s character, Max Basner, gets fired from his job as a clothing salesman. The scene, shot on a boat, shows Max’s despair about being out of work. I was looking for some gesture that would allow Max to show his feelings.

Jackie had far more experience at everything than I did, and at first I was frightened. What could I possibly tell “The Great One” about acting? Finally I decided to direct by suggestion, and sat down with Gleason to talk about the scene. “So Max is sad, right?” I said.

Gleason nodded.

“And he’s probably still carrying his pens with name on them—the ones he used to hand out to his customers, right?”

Gleason nodded.

“So what would you want to do with the pens after you were fired?”

He was silent for a moment. “Why don’t I throw them overboard?”

I stood up and turned up and turned toward the crew. “Hey, everybody, Jackie has a wonderful idea. Let’s shoot it.”

After filming the scene, Gleason called me over and said with a smile. “Garry, what kind of wonderful idea am I going to have tomorrow?”

You and your team can discover the answers to problems together. When there are no prizes or gold stars for who gets the solution first, you’ll all benefit when everything turns out right.
