O.Henry,born in Greensboro,North Carolina,was the pen name of William Sydney Porter.His father,Algernon Sidney Porter,was a physician.When William was three years old,his mother died,and he was raised by his grandmother and aunt.William was a good reader,but at the age of fifteen he left school,and worked in a drug store and later on a Texas farm.After that,he moved to Houston,where he had a number of jobs,including that of bank clerk.After moving to Austin,Texas,in 1882,he married.

In 1884 he started a humorous weekly The  Rolling Stone.When the weekly failed,he joined The  Houston Post as a reporter and columnist(专栏作家).In 1897 he was put into prison over some financial(财务的)dealings.While in prison,William started to write short stories to earn money to support his daughter Margaret.His first work,Whistling Dick’s Christmas Stocking(1899),appeared in McClure’s Magazine.After serving three years of the five years’ sentence,he changed his name to O.Henry,hoping to forget his bitter past.

O.Henry moved to New York City in 1902 and from December 1903 to January 1906 he wrote a story a week for the New York World,and also published the stories in other magazines.His first collection,Cabbages and Kings,appeared in 1904.Many other works quickly followed,such as The Gift of the Magi and The Furnished Room.O.Henry’s best known work is The Ransom of Red Chief.His stories always have surprising endings.He published 10 collections and over 600 short stories during his lifetime.

O.Henry’s last years were shadowed by drinking,ill health,and financial problems.In 1907,he experienced a failed marriage.In 1910,O.Henry died after an illness.

填空题

硫酸盐在生产生活中有广泛应用。

Ⅰ.工业上以重晶石(主要成分BaSO4)为原料制备BaCl2,其工艺流程示意图如下:

某研究小组查阅资料得:

BaSO4(s)+4C(s) 4CO(g)+BaS(s)△H1=+571.2kJ•mol-1      ①

BaSO4(s)+2C(s)2CO2(g)+BaS(s)△H2=+226.2kJ•mol-1      ②

(1)用过量NaOH溶液吸收气体,得到硫化钠。该反应的离子方程式是         

(2)反应C(s)+CO2(g) 2CO(g)的△H=           

(3)实际生产中必须加入过量的炭,同时还要通入空气,其目的有两个

①从原料角度看,                           

②从能量角度看,①②为吸热反应,炭和氧气反应放热维持反应所需高温。

(4)该小组同学想对BaSO4在水中的沉淀溶解平衡做进一步研究,查资料发现在某温度时BaSO4在水中的沉淀溶解平衡曲线如图所示。

该小组同学提出以下四种观点:

①当向含有SO42-的溶液中加入Ba2+ 使SO42-沉淀完全,则此时SO42-在溶液中的浓度为0

②加入Na2SO4可以使溶液由a点变到b点

③通过蒸发可以使溶液由d点变到c点

④d点无BaSO4沉淀生成

其中正确的是   (填序号)。

Ⅱ.某燃料电池以CaHSO4固体为电解质传递H+,其基本结构如图所示,电池总反应可表示为2H2+O2═2H2O。

请回答:

(5)H+   极通过固体酸电解质传递到另一极(填a或者b)。

(6)b极上发生的电极反应是
