南充高考可以复读吗入学检测化学选择题摘录
1、为防止新配制的FeCl2溶液变质，应向溶液中加入的物质是
A．碳粉 B．硫磺 C．铜粉 D． 铁粉
【知识点】铁和铁的化合物
【答案】
【答案】D
考点：以Fe的化合物为载体考查氧化还原反应。
2、下列说法不正确的是（ ）
A．晶体熔点由低到高：CF4＜CCl4＜CBr4＜CI4
B．熔沸点由大到小：金刚石＞碳化硅＞晶体硅
C．沸点由高到低：HI＞HBr＞HCl＞HF
D．硼镁超导物质的晶体结构单元如图所示，则这种超导材料的化学式为MgB2
【知识点】化学键
【答案】
【考点】不同晶体的结构微粒及微粒间作用力的区别．
【分析】A．分子晶体的相对分子质量越大，熔沸点越大；
B．键长越短，共价键越强，硬度越大；
C．HF分子间存在氢键，沸点较高；
D．利用均摊法计算．
【解答】解：A．分子晶体的相对分子质量越大，熔沸点越大，则晶体熔点由低到高顺序为CF4＜CCl4＜CBr4＜CI4，故A正确；
B．键长越短，共价键越强，硬度越大，键长C﹣C＜C﹣Si＜Si﹣Si，则硬度由大到小为金刚石＞碳化硅＞晶体硅，故B正确；
C．分子晶体的相对分子质量越大，熔沸点越大，HF分子间存在氢键，沸点较高，则沸点由高到低：HF＞HI＞HBr＞HCl，故C错误；
D．该晶胞中Mg原子个数=12×
+2×
=3，B原子个数=6，则Mg、B原子个数之比=3：6=1：2，据此确定化合物的化学式为MgB2，故D正确；
故选C．
3、为实现下列实验目的，依据下表提供的主要仪器，所用试剂合理的是 ( )
| 选项 | 实验目的 | 主要仪器 | 试剂 |
| A | 分离Br2和CCl4混合物 | 分液漏斗、烧杯 | Br2和CCl4混合物、蒸馏水 |
| B | 鉴别葡萄糖和蔗糖 | 试管、烧杯、酒精灯 | 葡萄糖溶液、蔗糖溶液、银氨溶液 |
| C | 实验室制取H2 | 试管、带导管的橡皮塞 | 锌粒、稀HNO3 |
| D | 测定NaOH溶液浓度 | 滴定管、锥形瓶、烧杯 | NaOH溶液、0.100 0 mol·L－1盐酸 |
【知识点】物质的分离 提纯和检验
【答案】
解析 A项，分离Br2和CCl4混合物应采用蒸馏法，由于Br2易溶于CCl4，难溶于水，故不能用水萃取CCl4中的Br2，不合理；B项，葡萄糖溶液与银氨溶液混合后水浴加热产生银镜，而蔗糖溶液与银氨溶液混合后水浴加热不产生银镜，合理；C项，锌与稀硝酸反应不能生成H2，不合理；D项，试剂中缺少指示剂酚酞，不合理。

1、 How to Be a Winner
Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
“In 1997 I was found to have developed diabetes （糖尿病） . Believing my career （职业生涯）was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it----the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn’t finished yet. Nothing is to stand in my way.”
Karen Pickering
Swimming World Champion
“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success―you can’t follow a career in any field without being well-organized. List what you believe you can achieve. “Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”
Kirsten Best
Poet ＆ Writer
“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological （心理的） tool.”
