把煤作为燃料可通过下列两种途径：

途径I：直接燃烧：C(s)＋O₂(g) = CO₂(g)

途径II：先制水煤气：C(s) + H₂O(g) =" CO(g)" + H₂(g)

燃烧水煤气：2 CO(g) + O₂(g)=2CO₂(g)；    2H₂(g)+O₂(g) = 2H₂O(g)

已知：①C(s)＋O₂(g) = CO₂(g)；△H₁=－393.5kJ·mol^-1

②H₂(g) + 1/2 O₂(g) = H₂O(g)；△H₂=－241.8kJ·mol^-1

③CO(g) + 1/2 O₂ (g)= CO₂(g)；△H₃=－283.0kJ·mol^-1

请回答下列问题：

（1）C（煤）的标准燃烧热是                  

（2）根据盖斯定律写出煤和气态水生成水煤气的热化学方程式：                  

（3）在制水煤气反应里，反应物具有的总能量________（填“＞”、“＜”或“＝”）生成物所具有的总能量。

（4）根据两种途径，下列说法错误的是              (单选)

A．途径II制水煤气时增加能耗，故途径II的做法不可取

B．与途径I相比，途径II可以减少对环境的污染

C．与途径I相比，途径II可以提高煤的燃烧效率

D．将煤转化为水煤气后，便于通过管道进行运输

The history of African—Americans during the past 400 years is traditionally narrated (1) an ongoing struggle against (2) and indifference on the part of the American mainstream, and a struggle (3) as an upward movement is (4) toward ever more justice and opportunity.

Technology in and of (5) is not at fault; it’s much too simple to say that gunpowder or agricultural machinery or fiber optics (6) been the enemy of an (7) group of people. A certain machine is put (8) work in a certain way—the purpose (9) which it was designed. The people who design the machines are not intent on unleashing chaos; they are usually trying to (10) a task more quickly, cleanly, or cheaply, (11) the imperative of innovation and efficiency that has ruled Western civilization (12) the Renaissance.

Mastery of technology is second only (13) money as the true measure of accomplishment in this country, and it is very likely that by (14) this under-representation in the technological realm, and by not questioning and examining the folkways that have (15) it, blacks are allowing.

Inner-city blacks in particular are in danger, and the beautiful suburbs (18) ring the decay of Hartford, shed the past and learn to exist without contemplating or encountering the tragedy of the inner city.

And blacks must change as well. The ways that (19) their ancestors through captivity and coming to freedom have begun to loose their utility. If blacks (20) to survive as full participants in this society, they have to understand what works now.
