题目:

对含微量I-的某样品进行I-化学定量测定,有以下两种途径,最后均是以淀粉作指示剂,用Na2S2O3标准溶液滴定以求得I-的浓度。下列分析正确的是

已知:5I-+IO3-+6H+=3H2O+3I2  I-+3Br2(过量)+3H2O=6H++6Br-+IO3-

方法一I-(样品)IO3-I2I-

方法二I-(样品)I2I-

A.方法二对样品所做处理操作简便,用作微量的测定更准确

B.当待测液由无色变为蓝色时即达到滴定终点

C.方法一与方法二测量出的样品浓度比为6:l

D.假设各步骤操作均得当,方法一所消耗Na2S2O3标准溶液的体积是方法二的6倍

It was the summer of 1965. Deluca, then 17, visited Peter Buck, a family friend. Buck asked Deluca about his plan for the future. “I'm going to college, but I need a way to pay for it,” Deluca recalls saying, “Buck said, ‘you should open a sandwich shop.’”

That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $1,000. Deluca rented a storefront (店面) in Connecticut, and when they couldn't cover their start­up costs, Buck kicked in another $1,000.

But business didn't go smoothly as they expected. Deluca says, “After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls.” All he and Buck knew was that their sales were lower than their costs.

Deluca was managing the store and to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. “We convinced ourselves to open a second store. We figured we could tell the public, ‘We are so successful; we are opening a second store.’” And they did—in the spring of 1966. Still, it was a lot of learning by trial and error.

But the partners' learn­as­you­go approach turned out to be their greatest strength. Every Friday, Deluca would drive around and hand­deliver the checks to pay their supplies. “It probably took me two and a half hours and it wasn't necessary but as a result, the suppliers got to know me very well, and the personal relationships established really helped out,” Deluca says.

And having a goal was also important. “There are so many problems that can get you down. You just have to keep working toward your goal,” Deluca adds.

Deluca ended up founding Subways Sandwich, the multimillion­dollar restaurant chain.

B.had succeeded in their business

C.wished to meet the increasing demand of customers

D.wanted to make believe that they were successful小题4:What contributes most to their success according to the author?
