       How do you get a man to do his share of the housework? If you are like most women, you’ve faced this question the hard way.

A man will enjoy a clean, orderly house, but he usually won’t make the effort to clean or organise it. This doesn't mean that a woman has to do all the housework:; she may have to manage many of the household duties, and request her partner’s participation(参与). A woman can often say that men and women should take equal responsibility(责任) for housework.

Very few men are raised to be fully responsible for housework, and many men look on housework as women’s work. On the other hand, most men will readily work around the yard, make repairs and complete projects on weekends or evenings, and it’s important that you give your man appreciation for those things, too. Most men will take on a little additional housework around the house if asked politely. They are even more likely to do housework if they can choose what they want to do, and do it without being monitored.

Here’s the key: men want to feel that they are doing housework either because they want to do a task, or because they simply want to please their women. Men are much less likely to take on household tasks they consider uninteresting and unimportant. In other words, men are likely to do a household task just for the good of the house.

I.我国即将建成自己的载人空间站。载人航天器的生态系统中,不仅要求分离去除CO2,还要求提供充足的O2

⑴某种电化学装置可实现如下转化:2CO2=2CO+O2,CO可用作燃料。已知该反应的某极反应为:4OH--4e-=O2↑+2H2O,则另一极反应为:           

⑵有人提出,可以设计某温度下的反应:2CO=2C+O2(△H>O、△S<O)来消除CO的污染。请你判断该温度下上述反应是否能发生并说明理由是                

Ⅱ.大气固氮属于自然固氮,合成氨是目前人工固氮的主要方法。科学家一直致力“人工固氮”新方法的研究。

⑴有关大气固氮(以N2+O  2NO为例)、人工固氮(以N2+3H2 2NH3为例)反应的平衡常数的值如下表。

反应N2+02 2NO        N2+3H22NH3
温度/℃ 272000100400
K 3.84×10-31 0.13.4×1092.0x104
下列说法正确的是           。(填字母)

a.大气固氮与人工固氮都是放热反应

b.人类模拟大气固氮无现实意义

c.寻找在常温下合成氨的高效催化剂是目前人工固氮的新方向

d.在常温下,人工固氮非常容易进行

⑵已知:N2(g)+3H2(g)  2NH3(g)    =-92.4kJ·mol-1

2H2(g)+02(g)="2H20(1)        " ="-571.6" kJ·mol-1

据报道,在常温、常压、光照、催化剂的条件下,N2可以与水反应,则反应 N2(g)+3H20(1)=2NH3(g)+3/2O2(g)的=          KJ·mol-1

⑶某研究小组在673 K、30 MPa下,在体积为的密闭容器中进行反应:N2(g)+3H2(g) 2NH3(g),其(H2)和(NH3)随时间变化的关系如图所示。

①下列叙述正确的是           。(填字母)

A.点a的正反应速率比点b的大

B.点c处反应达到化学平衡状态

C.若t3时由673 K升至773 K,则(H2)将增大

②从开始到平衡时反应的平均速率(以H2的浓度变化表示)(H2)=              

③若开始时(N2)=(H2),则反应的平衡常数=            (用代数式表示)。
