鸡蛋壳的主要成分是碳酸钙，为了测定蛋壳中碳酸钙的质量分数，小刚和小勇同学进行了如下实验：

（1）他俩将蛋壳洗净、干燥并捣碎放在烧杯里，然后往烧杯中加入足量盐酸，在蛋壳上很快就有很多小气泡产生，将收集到的气体通入澄清石灰水中，石灰水变浑浊．据此可判断收集到的气体中含有．

（2）实验过程和测定的相关实验数据如下图所示：

小刚根据“蛋壳残渣4.3g”，求得蛋壳中碳酸钙质量分数为．

小勇根据“反应过程中减少的质量”（10g+100g-106.7g=3.3g）也求得了蛋壳中碳酸钙的质量分数，请你写出小勇的计算过程和结果．

（3）小刚和小勇根据不同的数据求得蛋壳中碳酸钙的质量分数有明显差别，请你分析其中可能的原因．

     Most people think zoos are safe for animals , where struggles such as difficulty in finding food and

avoiding natural enemies don't exist . Without such problems , animals in zoos should live to an old age .

But that may not be true for the largest land animals on earth . Scientists have known that elephants in

zoos often suffer from poor health . They develop diseases and behaviour changes . Sometimes , they

even become infertile , or unable to have babies .

     To learn more about how elephants are affected , a team of international scientists compared the life

spans of elephants born in zoos with those living outdoors in their native lands . Zoos keep detailed

records of all the animals , such as birth dates , illnesses , weight and death . These records made it

possible for the researchers to analyse 40 years of data on 800 African and Asian elephants in zoos

across Europe . The team found that female African elephants born in zoos lived an average of 16.9

years while those in the wild lived an average of 56 years . Scientists don't yet know why wild elephants

seem to be so much better than their zoo-raised elephants . Georgia Mason , a biologist who led the

study , thinks stress and obesity may be to blame . Zoo elephants don't get the same kind of exercise they would in the wild , and most are fat .

     Another finding from the study showed that Asian elephants born in zoos were more likely to die early

than Asian elephants caught in the wild and brought to zoos . Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive .
