同类题2

合理地开发和利用资源、能源,节能减排,保护环境,是人类社会可持续发展的基础.氢气是理想的能源之一,科学家最近研制出利用太阳能产生激光、并在二氧化钛( TiO2)表面使海水分解得到氢气的新技术.

(1)水分子分解时,断裂的化学键是H﹣O键,此时需要____ (填“放出”或“吸收”)能量.水分解生成氢气和氧气的反应属于____ (填“放热”或“吸热”)反应.

(2)氢气是理想的清洁燃料的原因主要有:一是其完全燃烧放出的热量是等质量汽油完成燃烧放出热量的3倍多,二是制取它的原料是水、资源不受限制,三是它____ ,不会污染环境.生物质含有葡萄糖、淀粉和纤维素等糖类,也称碳水化合物,绿色植物将二氧化碳和水变成碳水化合物的过程称为____ 

(3)氢能开发的首要问题是研究如何以水为原料制取氢气.下列有关制取氢气的研究方向可行的是____ (填字母).

a.组成水的氢、氧都是可燃的,可以研究在水不分解的情况下,使氢气成为燃料

b.寻找高效的催化剂,使水分解产生氢气,同时释放出热量

c.寻找特殊化学物质,用于开发廉价能源,以分解水制取氢气

d.寻找更多的化石燃料,利用其燃烧放热,使水分解产生氢气

(4)汽车或某些工业生产的尾气中含有的氮氧化物NOx(即NO和NO2的混合物),对生态环境和人类健康带来较大的威胁.

①大量的氮氧化物排放到空气中会导致的主要环境问题有形成酸雨、____ (填﹣项).

②已知在催化剂和加热条件下,NO与NH3反应的化学方程式为:6NO+4NH35N2+6H2O

某研究小组按下列过程探究不同催化剂对NH3还原NO反应的催化性能:

若控制其他实验条件均相同,在催化反应器中装载不同的催化剂,将经催化反应后的混合气体通入滴有酚酞试液的稀硫酸溶液(溶液的体积、浓度均相同).为比较不同催化剂的催化性能,需要测量并记录的数据是____ 

③工业上常用Na2CO3溶液吸收处理某些尾气中的NOx.己知:

NO不能直接与Na2CO3溶液反应;

NO+NO2+Na2CO3═2NaNO2+CO2

2NO2+Na2CO3═NaNO2+NaNO3+CO2

则当NOx被Na2CO3溶液完全吸收时,x的取值范围是____
