工业上电解饱和食盐能制取多种化工原料,其中部分原料可用于制备多晶硅.

(1)图是离子交换膜法电解饱和食盐水示意图,电解槽阳极产生的气体是______;NaOH溶液的出口为______(填字母);精制饱和食盐水的进口为______(填字母);干燥塔中应使用的液体是______.

(2)多晶硅主要采用SiHCl3还原工艺生产,其副产物SiCl4的综合利用收到广泛关注.

①SiCl4可制气相白炭黑(与光导纤维主要原料相同),方法为高温下SiCl4与H2和O2反应,产物有两种,化学方程式为______.

②SiCl4可转化为SiHCl3而循环使用.一定条件下,在20L恒容密闭容器中的反应:3SiCl4(g)+2H2(g)+Si(g)

4SiHCl3(g)达平衡后,H2与SiHCl3物质的量浓度分别为0.140mol/L和0.020mol/L,若H2全部来源于离子交换膜法的电解产物,理论上需消耗纯NaCl的质量为______kg.
