题型：实验题

（12分）某实验小组用0.50 mol·L-1 NaOH溶液和0.50 mol·L-1硫酸溶液进行中和热的测定。

Ⅰ．配制0.50 mol·L-1 NaOH溶液

（1）若实验中大约要使用245 mL NaOH溶液，至少需要称量NaOH固体            g。

（2）从下图中选择称量NaOH固体所需要的仪器是（填字母）：                   。

Ⅱ．测定稀硫酸和稀氢氧化钠中和热的实验装置如右图所示。

Ⅱ．中和热的测定：

（3）从实验过程来看，图中尚缺少的两种玻璃仪器是    __、________；

（4）取50 mL NaOH溶液和30 mL硫酸溶液进行实验，实验数据如下表。

①请填写下表中的空白：

②近似认为0.50 mol/L NaOH溶液和0.50 mol/L硫酸溶液的密度都是1 g/cm3，中和后生成溶液的比热容c =" 4.18" J/(g·℃)。则中和热△H=                 （取小数点后一位）。

③上述实验数值结果与57.3 kJ/mol有偏差，产生偏差的原因可能是（填字母）       。

a．实验装置保温、隔热效果差

b．配制0.50 mol/L NaOH溶液时俯视刻度线读数

c．分多次把NaOH溶液倒入盛有硫酸的小烧杯中

d．用温度计测定NaOH溶液起始温度后直接测定H2SO4溶液的温度

e．用量筒量取NaOH溶液的体积时仰视读数

（5）实验中改用30 mL 0.50 mol/L的硫酸跟50mL 0.55 mol/L的NaOH溶液进行反应，与上述实验相比，所放出的热量       （填“相等”或“不相等”），所求中和热的数值会    __________（填“相等”或“不相等”）。

Passage One

Historically, although the children of immigrants may have grown up bilingual and bicultural, many did not pass on much of their parents’ language or culture to their own children. Thus, many grandchildren of immigrants do not speak the language of the old country and are "American" by culture. However, in some parts of the country with established communities that share a common language or culture, bilingualism and biculturalism continue. This is particularly true in communities where new immigrants are still arriving. In general, cultural pluralism (多元化) is more accepted in the United States today than it was in the first half of the 20th century, and many of the school systems have developed bilingual programs and multicultural curricula.
At the close of the 20th century, there seemed to be a rise in the consciousness of ethnic groups around the world, and a sense of pride in what makes them unique. This occurs in the United States among many different groups, and in some cases it has resulted in new names to symbolize each group’s identity. In the United States, people have become very sensitive to the language used to describe these groups, and they try to be "politically correct" (P. C. ). For example, many black Americans, particularly young people, prefer the term African-American instead of black, to identify with their African heritage. Some Spanish speakers prefer to be called Latinos (referring to Latin America) instead of Hispanics, while others prefer to be identified by their country of origin (Cuban-American or Cuban, Chicano, Mexican-American or Mexican, and so on).
In spite of some very important differences, however, there is still a tie that binds Americans together. That tie is a sense of national identity—of "being an American". Incidentally, when citizens of the United States refer to themselves as Americans, they have no intention of excluding people from Latin American countries. There is no word such as United Statesians in the English language, so people call themselves Americans. Thus, what is really a language problem has sometimes caused misunderstandings. Although citizens of Latin American countries may call the people in the United States North Americans, to most people in the United States this makes no sense either, because the term North Americans refer to Canadians and Mexicans as well as citizens of the United States. The word American, then, will be used in this text as the adjective and nationality for the people who live in the United States of America.

This passage is mainly concerned with ______ .

A．cultural pluralism in the U. S.

B．African Americans in the U. S.

C．history of immigrants in the U. S.

D．new immigrants in the U. S.
