對金屬與酸反應問題考查的常見題型的分析

在對金屬的化學性質考查中,其中金屬與酸反應是中考的熱點,但同時也是一個難點,F將中考化學中的這一知識點加以整理,供同學們參考。

金屬與酸發生置換反應的條件:

(1)對金屬的要求:必須是金屬活動性順序中排在氫以前的金屬;

(2)對酸的要求:這里所指的酸并不是所有的酸,主要是指稀鹽酸和稀硫酸。

 

金屬與酸反應產生H2的規律:(1)質量為m,相對原子質量為M,化合價為+n(指在生成物中的化合價)的金屬與足量酸反應,產生的氫氣的質量x=nm/M

 

 即:H2的質量=金屬的質量×金屬在化合物中的化合價/該金屬的相對原子質量

 

 (2)等質量的幾種金屬與足量酸反應產生的H2質量與該金屬的 化合價/相對原子質量 的值成正比 ,該值越大,產生的H2質量越多,該值越小,產生的H2質量越小。

A

There was a story many years ago of a school teacher―Mrs. Thompson. She told the children on the first day that she loved them all the same. But that was a lie. There in the front row was a little boy named Teddy Stoddard. He didn’t play well with the other children and he always needed a bath. She did not like him.

Then Mrs. Thompson got to know that Teddy was actually a very good boy before the death of his mother. Mrs. Thompson was ashamed of herself. She felt even worse when, like all her other students, Teddy brought her a Christmas present too. It was his mother’s perfume(香水).

Teddy said, “Mrs. Thompson, today you smell just like my Mom used to.” After the children left she cried for at least an hour. On that very day, she stopped teaching reading, writing and math. Instead, she began to teach children.

Mrs. Thompson paid particular attention to Teddy. The boy’s mind seemed to come alive. The more she encouraged him, the faster he improved. By the end of the sixth grade, Teddy had become one of the smartest children in the class.

Six years went by before she got a mote from Teddy. He wrote that he had finished high school, third in his class, and she was still the best teacher he ever had in his whole life. He went to college. Mrs. Thompson got two more letters from him with the last one signed, Theodore F. Stoddard, M. D.(醫學博士).

The story doesn’t end there. On his wedding day, Dr. Stoddard whispered in Mrs. Thompson’s ear, “Thank you, Mrs. Thompson, for believing in me. You made me feel important and showed me that I could make a difference.”

Mrs. Thompson, with tears in her eyes, whispered back, “Teddy, you have it all wrong. You were the one who taught me that I could make a difference. I didn’t know how to teach until I met you.”

56.What did Mrs. Thompson find out about Teddy?

A.He often told lies.                   B.He was good at math.

C.He needed motherly care.             D.He enjoyed playing with others.

57.In what way did Mrs. Thompson change?

A.She taught fewer school subjects.         

B.She became stricter with her students.

C.She no longer liked her job as a teacher.  

D.She cared more about educating students.

58.Why did Teddy thank Mrs. Thompson at his wedding?

A.She had kept in touch with him.        B.She had given him encouragement.

C.She had sent him Christmas presents.    D.She had taught him how to judge people.

      Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.

      “I would never have said to my mom, ‘Hey, the new Weezer album is really great. How do you like it?’” says Ballmer. “There was just a complete gap in taste.”

      Music was not the only gulf. From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.

      Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood.

      No wonder greeting cards today carry the message, “ To my mother, my best friend.”

      But family experts warn that the new equality can also result in less respect for parents.

      “There’s still a lot of strictness and authority on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College, “In the middle of that change, there is a lot of confusion among parents.”

      Family researcher offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say.

      “ My parents were on the ‘before’ side of that change, but today’s parents, the 40-year-old, were on the ‘after’ side,” explains Mr. Ballmer. “It’s not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now.”

      62.The underlined word gulf in para. 3 most probably means __________.

      A.interest          B.distance        C.difference       D.separation

      63.Which of the following shows that the generation gap is disappearing?

      A.Parents help their children develop interests in more activities.

      B.Parents put more trust in their children’s abilities.

      C.Parents and children talk more about sex and drugs.

      D.Parents share more interests with their children.

      64.The change in today’s parent-child relationship is __________.

      A.more confusion among parents

      B.new equality between parents and children

      C.less respect for parents from children

      D.more strictness and authority on the part of parents

      65.The purpose of the passage is to ___________.

      A.describe the difficulties today’s parents have met with

      B.discuss the development of the parent-child relationship

      C.suggest the ways to handle the parent-child relationship

      D.compare today’s parent-child relationship with that in the past

      D

      Sometimes you’ll hear people say that you can’t love others until you love yourself. Sometimes you’ll hear people say that you can’t expect someone else to love you until you love yourself. Either way, you’ve got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’ eyes, and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics. but sometimes it’s a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.

      Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

      The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubts to occur in it.

      It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.

      The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍)yourself on the back, you’ll know you’re well on your way. Good luck !

      66.You need to build a positive self-image when you _____________.

      A.dare to challenge yourself            B.feel it hard to change yourself

      C.are unconfident about yourself        D.have a high opinion of yourself

      67.According to the passage, our self-images __________.

      A.have positive effects                B.are probably untrue

      C.are often changeable                D.have different functions

      68.How should you change your self-image according to the passage?

      A.To keep a different image of others.        B.To make your life successful.

      C.To understand your own world.           D.To change the way you think.

      69.What is the passage mainly about?

      A.How to prepare for your success.           B.How to face challenges in your life.

      C.How to build a positive self-image.         D.How to develop your good qualities.

      70.Who are the intended readers of the passage?

      A.Parents.                    B.Adolescents /Teenagers.

      C.Educators.                  D.People in general.

      A 10-year-old boy decided to learn judo despite the fact that he had lost his left arm in a car accident.

      The boy began lessons with an old Japanese judo teacher. The boy was doing well, so he couldn’t understand why, after three months of training, the master had taught him only one move.

      “ Master,” the boy finally said, “shouldn’t I be learning more moves?”

      “ This is the only move you know, but this is the only move you’ll ever need to know,” the teacher replied.

      Not quite understanding, but believing in his teacher, the boy kept training.

      Several months later, the teacher took the boy to his first tournament.

      Surprising himself, the boy easily won his first two matches. The third match proved to be more difficult, but after some time, his opponent became impatient and charged; the boy skillfully used his one move to win the match. Still amazed by his success, the boy was now in the final.

      This time, his opponent was bigger, stronger, and more experienced. For a while, the boy appeared to be overmatched. Concerned that the boy might get hurt, the judge called a time-out. He was about to stop the match when the teacher appeared.

      “ No,” the teacher insisted, “Let him continue.”

      Soon after the match continued, his opponent made a mistake: he dropped his guard. Instantly, the boy used his move to pin him. The boy won the match and the tournament. He was the champion.

      On the way home, the boy and the teacher reviewed every move in each and every match. Then the boy got up the courage to ask what was really on his mind.

      “ Teacher, how did I win the tournament with only one move?”
