    As we know, museums are buildings where many valuable and important objects are kept so that people can
go and see them. For example, art museums are places where people can learn about 9 (1) v______ cultures.
More and more popular "design museums" that are opening today, however, perform quite a different role.
(2) U______ most art museums, the design museum shows objects that are easily found in our daily life, such
as fridges and washing machines.
    The (3) a______ of design museums is that they are places where people feel familiar with the exhibits(展品).Being different from the art museum visitors, design museum visitors (4) s______ feel frightened or puzzled.
This is partly because design museums clearly show how and why mass-products (批量产品) work and look
as they do, and how design has (5) i______ the quality of our lives. Art museum exhibits, on the other hand,
would most probably fill visitors with a feeling that there is something (6) b______ their understanding.
   Several new design rnuseums have opened their doors in (7) r______years. Each of these museums has tried
to satisfy (满足) the public's growing interest in the field with new (8) i_____. London's Design Museum, for
example, shows a collection of mass-produced objects from electric typewriters to a group of Italian fish-tins.
The choices open to design museums seem (9) f_______ less strict than those to art museums, and visitors
may also sense (感觉到) the humorous part of our society while walking around such exhibits as interesting and
unusually attractive toys (10) c______ from our everyday life.

研究NO₂、SO₂、CO等大气污染气体的处理及利用的方法具有重要意义。

⑴一定条件下，NO₂与SO₂反应生成SO₃和NO两种气体。将体积比为1∶2的NO₂、SO₂气体置于密闭容器中发生上述反应，下列能说明反应达到平衡状态的是________(填字母)。

a.体系压强保持不变 b.混合气体颜色保持不变

c.体系中SO₃的体积分数保持不变 d.每消耗1 mol SO₂的同时生成1 mol NO

测得上述反应平衡时NO₂与SO₂体积比为1∶6，则平衡常数K＝________。

⑵新型氨法烟气脱硫技术的化学原理是采用氨水吸收烟气中的SO₂，再用一定量的磷酸与上述吸收产物反应。该技术的优点除了能回收利用SO₂外，还能得到一种复合肥料，该复合肥料可能的化学式为________(写出一种即可)。

⑶右图是MCFC燃料电池，它是以水煤气(CO、H₂)为燃料，一定比例Li₂CO₃和Na₂CO₃低熔混合物为电解质。A为电池的________(填“正”或“负”)极，写出B极电极反应式：________________________。

⑷工业上常用Na₂CO₃溶液吸收法处理氮的氧化物(以NO和NO₂的混合物为例)。

已知：NO不能与Na₂CO₃溶液反应。

NO＋NO₂＋Na₂CO₃=2NaNO₂＋CO₂

2NO₂＋Na₂CO₃=NaNO₂＋NaNO₃＋CO₂

①用足量的Na₂CO₃溶液完全吸收NO和NO₂的混合物，每产生22.4 L(标准状况)CO₂(全部逸出)时，吸收液质量就增加44 g，则混合气体中NO和NO₂的体积比为

____________。

②用Na₂CO₃溶液吸收法处理氮的氧化物存在的缺点是____________。
