Nitric acid is a component of acid rain that forms when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid.
Write a balanced chemical equation for this reaction.
Express your answer as a chemical equation. Identify all of the phases in your answer
I put this 4HNO3
and I got this as a request

What am I doing wrong?
The literature gives this as the reaction of NO2 gas with water vapor to form nitrous and nitric acids.
2NO2(g) + H2O(l) ==> HNO2(aq) + HNO3(aq)
However that doesn't show O2 as a reactant.
Another place I see that HNO3 decomposes to O2, NO2, and H2O and if we reverse that an balance it we get this.
4NO2(g) + O2)g) + 2H2O(l) ==> 4HNO3(aq)
which is about as close as I can come to it. There are numerous other reactions in the literature but none specifically with the reagents in the problem. I hope this helps.
thank you
To write a balanced chemical equation, you need to ensure that both sides of the equation have an equal number of atoms for each element involved. In the case of forming nitric acid from nitrogen dioxide, oxygen, and water, the balanced equation is as follows:
2NO2(g) + O2(g) + 2H2O(l) -> 4HNO3(aq)
In this equation, the "2" in front of NO2 and H2O represents the balanced coefficients, indicating that two molecules of NO2 and two molecules of H2O are needed to form four molecules of HNO3. Additionally, the (g) and (l) notations represent the phase of each substance (gaseous and liquid, respectively), while (aq) indicates that nitric acid is aqueous. Make sure you have correctly included the phases in your submission.
It seems like you are on the right track, but there may be a formatting error in your submission.
To write a balanced chemical equation for this reaction, you would need to consider the reactants and products involved. According to the given information, gaseous nitrogen dioxide (NO2), gaseous oxygen (O2), and liquid water (H2O) react to form aqueous nitric acid (HNO3).
The balanced chemical equation for this reaction can be written as:
4 NO2 (g) + 2 O2 (g) + 2 H2O (l) → 4 HNO3 (aq)
Make sure to use the correct chemical formulas and include the appropriate state symbols (g for gas, l for liquid, and aq for aqueous) for each reactant and product.
If the error message is still persisting, double-check your formatting and make sure you have inputted the reaction correctly.
