Help me balancing this equation! Grade 10

Post by mishu »

I am having trouble balancing this equation:

3 NO2 + H2O → 2H2NO3 + NO

And I even looked through online balancing calculators and they can't solve them..
Please if anybody can help me with this question I would immensely apreciate it.

This is the closest I got:

H2NO3 → NO2 + H2O

H2NO3 is not existing . Nitrogen is not hexavalent. It's only HNO2 or HNO3 existing.

NO2 dissolved in water gives

H2O + 2 NO2 => HNO3 + HNO2

Excuse me, one question, what do you mean when you say that H2NO3 is not existing?

That what it means , there is no H2NO3 in this world, because nitrogen is only pentavalent.

Nitrite Hydrate is negative charged. H2NO3-
You wrote a neutral molecule H2NO3.
The neutral molecule is not existing.
As described in your link it is a compound with nitrite NO2- and water H2O.
You need also a positiv charge like sodium. So you would have NaNO2 with one water attached.
This is total different what you described before.
