How to Calculate Energy for Atmospheric Molecule Reaction and Isolate Gases?

AI Thread Summary
The discussion centers on the presence of carbon dioxide (CO2) and methane (CH4) in the atmosphere, both of which are viewed as harmful due to their contributions to global warming. A proposed chemical reaction, CH4 + CO2 --> 2H2O + C2, aims to address this issue, but questions arise regarding the energy required for the reaction and methods for isolating these gases from the atmosphere. Participants debate the concentrations of methane and CO2, the feasibility of the proposed reaction, and its thermodynamic favorability. While some argue that CO2 and methane are not toxic at atmospheric levels, concerns about elevated concentrations leading to health risks are acknowledged. The necessity of CO2 for plant life is also highlighted, countering the notion that it is purely harmful. Overall, the conversation emphasizes the complexity of addressing atmospheric gas concentrations and their environmental impacts.

The atmosphere consists of two toxic, and unfortunately abundant gases in our atmosphere. Carbon dioxide and methane. Carbon dioxide produced by factories are not needed in the atmosphere and cause harm. So is methane. Acegikmoqsuwy and I thought of an equation to solve this problem: CH4 + CO2 --> 2H2O + C2 . The part of this equation that needs some fixing is the first side. How do you calculate the energy required for this reaction? How do you isolate the gases in the atmosphere? I would be glad to get generous responses.

Do you know the relative concentrations of methane and CO2 in the atmosphere? Look them up, and then tell us whether you think that the reaction you suggest, if it could actually occur, would be effective. Do you think that the reaction you suggested would be favored thermodynamically, so that it would go nearly to completion?

You mentioned that methane is produced in factories. What fraction of the methane release to the atmosphere is produced in factories?
 
Neither carbon dioxide nor methane are toxic.

I wouldn't go that far.

It's true that breathing CO2and CH4 in the concentrations in which they are found in the atmosphere won't cause harm.

However, if one is exposed to an isolated atmosphere in which the concentration of CO2 is elevated, eventually the amount of CO2 in the bloodstream rises and makes the blood more acidic. This change in the blood gases can eventually cause convulsions and death if the concentration of CO2 is not lowered. That's why places where isolated atmospheres occur, like submarines or spacecraft , are equipped with chemicals to absorb CO2.

Of course, if an atmosphere contains only CO2 or CH4 and little or no oxygen, asphyxiation will result.

The OP apparently doesn't realize that some CO2 in the atmosphere is needed, lest all the plants die.

Point taken. But both CO2 and methane have very low toxicity.

I was primarily annoyed by the OP describing them as toxic while the main problem they can cause in the atmosphere is global warming.

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
