1 L of CO2 is passed through red hot coke. The volume becomes 1.4 L at same temperature and pressure. What is the composition of the product?

When carbon dioxide reacts with red hot coke, carbon monoxide is formed. The balanced chemical equation for this reaction can be written as:


`CO_2 + C -> 2CO`


Here, 1 mole of carbon dioxide reacts with 1 mole of coke to produce 2 moles of carbon monoxide. 


Let us assume that x liters of carbon dioxide are consumed in the reaction, then the remaining volume of carbon dioxide is 1-x liters.


Assuming STP conditions, 1...

When carbon dioxide reacts with red hot coke, carbon monoxide is formed. The balanced chemical equation for this reaction can be written as:


`CO_2 + C -> 2CO`


Here, 1 mole of carbon dioxide reacts with 1 mole of coke to produce 2 moles of carbon monoxide. 


Let us assume that x liters of carbon dioxide are consumed in the reaction, then the remaining volume of carbon dioxide is 1-x liters.


Assuming STP conditions, 1 l of CO2 = 1/22.4 moles


and x l = x/22.4 moles


Using stoichiometry,


x/22.4 moles of CO2 will produce 2x/22.4 moles of CO.


At STP, 2x/22.4 moles = 2x l (1 mole = 22.4 l at STP)


Thus, the final volume of gases will include the leftover CO2 and newly formed CO.


That is, 1-x + 2 x = 1.4 l


or, 1 + x = 1.4


or, x = 0.4 l


and 2x = 0.8 l


Thus, 0.8 l of CO are formed. And 0.6 l (= 1- x = 1- 0.4) of CO2 are left over.


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 did the United States become an imperial power?

"Imperial power" is a bit of a vague label. It tends to mean several things at once, so let's unpack it. In the sense of "this country was built on conquest by force," the "imperial power" part of America actually predates the United States proper. The territories that would become the United States were imperial colonies, established by the great European empires of the 17th and 18th centuries. Much of the US Constitution and American governance generally goes back to England, history's largest and most successful imperial power, but vital aspects of American culture come from other imperial powers, such as France and Spain. Much of American culture comes from sources other than the old empires, but they were key influences on what the United States became. In the sense of "this country treats conquest by force as a fundamental component of its culture, economy and politics," the United States has always been an imperial power. Even earl...

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,...

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...
