What are the products formed when nitrogen dioxide reacts with …
Both can take place, but nitrous acid is unstable. In warm or concentrated solutions, the nitrous acid will disproportionate, forming nitric oxide and more nitric acid. So the nitrous acid is essentially only a temporary intermediate.
atmospheric chemistry - Why does nitrous oxide have 300 times …
But even so, that means that the two peaks that matter are $\ce{CO2}$'s 700 peak, and $\ce{N2O}$'s 1300 peak. It is my understanding that the blackbody radiation of earth peaks at around 700, and though sizable, is much less at 1300. So, I don't see why nitrous oxide would have a greater global warming potential than carbon dioxide.
Why does copper react only with nitric acid? [duplicate]
2016年1月3日 · There are actually two equations for the reaction of copper with nitric acid. It depends on whether the nitric acid is concentrated or not. If it is concentrated and in excess then the ratio is 1:4 copper to nitric acid. If it is dilute then the ratio is 3:8. Cu +4HNOX3 3Cu +8HNOX3 Cu(NOX3)X2 +2NOX2 +2HX2O 3Cu(NOX3)X2 +2NO +4HX2O C u + 4 H N O ...
Why is nitrous acid prepared in situ? - Chemistry Stack Exchange
2017年5月5日 · HNO2 has an intermediate oxidation state of +3.Thats why,it tends to be disproportionate into more stable oxidation state. Instead of this,to prepare Nitrous acid,we take the mixture of NaNO2 and HCl. NaNO2+HCl→NaCl+HNO2. Through this process,HNO2 is prepared in the labratory in need. Share. Cite.
Nitric acid decomposition - Chemistry Stack Exchange
2017年6月30日 · 1. I have a problem with the decomposition reaction of Nitric acid (HNOX3 H N O X 3) by light. My problem: is that reaction is a redox reaction? If it is please tell me the oxidation and reduction (balanced) reactions seperately. inorganic-chemistry.
inorganic chemistry - How does Aluminum react with nitric acid at ...
2020年5月23日 · Providing the diluted acid contains dissolved sodium chloride and traces of copper(II) cations, a vigorous reaction occurs. The product is basically nitrous oxide (possibly containing some elemental hydrogen and nitrogen gases), and was identified by its IR spectrum.
Why is nitrogen dioxide brown? - Chemistry Stack Exchange
2017年11月20日 · Nitrogen Dioxide[NO2]: This here is its resonance structure/canonical structure. NO2 is a molecule in which a Nitrogen is connected with two atoms of Oxygen and its shape is Bent. Total number of valence electrons is 17 with each Oxygen atoms contributing 6 and 5 electrons are from Nitrogen.
inorganic chemistry - Stoichiometric reaction of hydrochloric acid ...
2017年2月19日 · The reaction should produce nitrogen dioxide ($\ce{NO2}$). The chemical equation should look like this: $$ \ce{HCl + KNO3 + Cu -> NO2} $$ But I'm clearly missing something. Can anybody help me equalize and complete this equation?
Why is NO2 formed when N valency is 3 - Chemistry Stack Exchange
2015年12月30日 · Here's what I know about chemical formula: Reverse the valencies of the combining elements. But in this case, NOX2 N O X 2 is the formula for nitrogen dioxide while N valency is 3. Please explain it to me if I am wrong somewhere. Your rule of swapping the valencies only works for a very specific set of compounds.
How does burning natural gas produce nitrogen oxides?
2023年1月30日 · Here is a starting point for further research. If your fuel is coal or oil, nitrogen-containing compounds in the fuel contribute substantially to the NOx load. Natural gas also contains dinitrogen, so even burning it in pure oxygen would produce NOx. The amount of NOx depends on various parameters of combustion, not just the temperature.
