How many grams of hydrogen will react with excess nitrogen to form 10.0 moles ammonia? How may moles of hydrogen must react with 56 grams of...

Hydrogen and nitrogen react to form ammonia. The relevant chemical equation can be written as:


`N_2 + 3H_2 -> 2NH_3`


Here 1 mole of nitrogen reacts with 3 moles of hydrogen to form 2 moles of ammonia. 


In the first case, excess nitrogen is present. Using stoichiometry,


2 moles ammonia requires 3 moles hydrogen,


1 mole of ammonia will require 3/2 moles of hydrogen


and 10 moles of ammonia will require 3/2 x 10 =...

Hydrogen and nitrogen react to form ammonia. The relevant chemical equation can be written as:


`N_2 + 3H_2 -> 2NH_3`


Here 1 mole of nitrogen reacts with 3 moles of hydrogen to form 2 moles of ammonia. 


In the first case, excess nitrogen is present. Using stoichiometry,


2 moles ammonia requires 3 moles hydrogen,


1 mole of ammonia will require 3/2 moles of hydrogen


and 10 moles of ammonia will require 3/2 x 10 = 15 moles of hydrogen.


The molar mass of hydrogen is 2 g.


Thus, 15 moles x 2 g/mole = 30 g of hydrogen is required to make 10 moles of ammonia.


Molar mass of nitrogen is 28 g and thus, 56 g of nitrogen contains 56 g / 28 (g/mole) =  2 moles.


Using the well balanced chemical equation for formation of ammonia, 1 mole of nitrogen reacts with 3 moles of hydrogen and thus, 2 moles of nitrogen will react with 2 x 3 = 6 moles of hydrogen.


Hope this helps.

In chapter one of The Great Gatsby, what advice does Nick's father give him? How does this make him a good person to tell this story?

Nick says that his father advised him that, before "criticizing anyone," he "remember that all the people in this world haven't had the same advantages" as Nick.  As a result, Nick claims that he is "inclined to reserve all judgments," presenting himself to the reader as a fair and dispassionate arbiter of character, and thus, a reliable narrator.   The problem is that Nick immediately reveals himself as anything but reliable, as he then launches...

How and why does James Gatz become Jay Gatsby? Describe the young Gatsby/Gatz.

James Gatz, a poor Midwestern boy of probable Jewish lineage, becomes Jay Gatsby, a presumed WASP and wealthy socialite, when he moves to New York City and acquires his fortune. It is wealth that has allowed Gatz to transform himself into Gatsby. However, those who know his background (e.g., Daisy and Tom Buchanan) never allow him to forget that he is nouveau riche -- that is, an upstart who has just recently made his fortune,... James Gatz, a poor Midwestern boy of probable Jewish lineage, becomes Jay Gatsby, a presumed WASP and wealthy socialite, when he moves to New York City and acquires his fortune. It is wealth that has allowed Gatz to transform himself into Gatsby. However, those who know his background (e.g., Daisy and Tom Buchanan) never allow him to forget that he is nouveau riche -- that is, an upstart who has just recently made his fortune, whereas they arose from well-to-do families. Gatz became Gatsby through determination and discipline. At the end of the novel, the narr...

Explain and discuss how the definitions of freedom change for the nation, for the freedmen and for southern whites after the Civil War.

After the Civil War, the definition of freedom changed in the nation, as slavery was ended with the 13th Amendment to the Constitution in 1865. The practice of slavery was disallowed, but definition of the freedom that would take its place was a subject of controversy, ongoing debate, and even violence in the decades to come.  For freedmen, freedom often meant reconciling with their families, who were broken up by slavery; choosing which church to...
