Students were asked to answer a question at schools and to mention what is most important for them to succeed. Of many results, one that that stood out was practice. People who were successful do not become successful by being born. They work hard and commitment their lives to succeeding. If you would like to attain your goals, keep this in mind! just below some question and answer examples that you possibly will make use of to enrich your knowledge and gain insight that will assist you to maintain your school studies.
In the reaction of nitrogen gas, N2, with hydrogen gas, H2, to form ammonia gas, NH3, how many moles of hydrogen are needed to react with two moles of nitrogen? N2 + 3H2 → 2NH3 Select one: A. 5.710 moles B. 4 moles C. 2 moles D. 8 moles E. 6 moles
Answer : The correct option is, (E) 6 moles.
Explanation : Given,
Moles of nitrogen = 2 moles
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of nitrogen gas react with 3 moles of hydrogen gas
So, 2 mole of nitrogen gas react with moles of hydrogen gas
Therefore, the number of moles of hydrogen gas needed to react with 2 moles of nitrogen gas is, 6 moles.
They would probably hopefully guide the student deal with the question by using the questions and answer examples. Then could potentially make some sharing in a group discussion and also study with the classmate concerning the topic, so another student also have some enlightenment and still keeps up the school learning.
