n(N2) = m(N2)/M(N2)

M(N2) = 2*14 = 28 г/моль

n(N2) = 55 г / 28г/моль = 1, 96 моль

A. There are lots of achievements to proud of.
B. Different actions were taken for one reason.
C. A lot of time was lost in protecting nature.
D. Nature protection has to struggle against industries.
E. The two aimed to help wildlife.
F. There was no time to lose.
1. More than a hundred years ago, two men who barely knew each other climbed up into the Sierra Nevada wilderness and spent four days exploring mountains and tracking wildlife. They saw elk and black bear, wild iris and larkspur. They drank from streams, slept on beds of pine needles, and awoke from a night camping on Glacier point to find four feet of sunrise snow. When they came down from the mountains, President Theodor Roosevelt and Sierra Club founder John Muir were good friends. Over their parting handshake they made a pact: They would work together to save America’s wilderness. And they did.
2. The United States had already lost most of its buffalo, tallgrass prairies, Eastern old-growth forests, and grizzly bears. Bold, immediate action was called for—and taken. Between 1901 and 1909, President Roosevelt and Congress created five national parks, established more than fifty wildlife reserves, and set aside 100 million acres of forest for protection. During the decade, the Sierra Club grew from a hiking club to a political force.
3. John Muir and the growing membership of his Sierra Club conducted guided tours to wild areas to win allies and public support for the preservation efforts, wrote letters and articles in newspapers, pioneered the use of public education, political accountability and lobbing, and legislation to protect the health of our environment. It was the Sierra Club that fled lawsuits to stop pollution in Lake Superior and developments in Everglades, and created books, films, photographs, and advertising for wilderness and wildlife protection.
4. Since its founding in 1892, the Sierra Club has also helped bring about the establishment of Yosemite and more than a score of other national parks; an end to government plans to dam the Colorado River and flood the Grand Canyon; the enactment of the Clean Water Act, Clean Air Act, and Endangered Species Act; the granting of national movement status for Utah’s Grand Staircase — Escalante, the giant sequoias of California’s Serra Nevada and many more national treasures in different parts of the country, including Alaska.
5. More than a century of national and local conservation campaigns has taught the Sierra Club that no place—despite its official designation, environmental value, or storied past—is ever completely protected. The oil companies, the logging industry, and developers never give up. And as the nation grows, the pressures to drill, log, and build in special places will also grow.
