Bubbling
Hi,
Any idea if the mixture of DI Water, H2O2 and NH4OH with the ratio 20:3:1 respectively creat bubbles when the mixture is agitated and heated up to 50
degrees celcius?

It probably will create bubbles (oxygen) due to the decomposition of the hydrogen peroxide.
Now seriously, you could have figured this out yourself very easily. I guess this is a chemistry homework or something?

It will also probably release ammonia (NH3) from the NH4OH.

Water will also be released (evaporation) to an extent.

If you consulted the literature you would have found hydrogen peroxide is destabilzed by high pH solutions. In the presense of metals the peroxide is
unstable in even strongly acid solutions.

I read that H2O2 can oxidize ammonia to ammonium nitrite which decomposes to nitrogen. Is this true?

No, its not possible as far as i know, under any conditions of reaction. I do know for sure that just adding a H2O2 solution to an ammonia solution
WILL NOT just react with each other
Ammonium nitrite does decompose into nitrogen. but if it is nitrogen gas you are trying to get, then there are some ways you can do it.
the first one is:
NaNO2 + NH4Cl = NaCl + 2H2O + N2
this one is done pretty easily from what i understand, but i have never done it so i cant really say.
And the second one is from this nice little site with a few other chemistry stuff on it
http://www.douchermann.a0tu.com/General_Chemistry.html#n2
The main reaction in this one is simply 4NH3(aq) + 3Ca(OCl)2(s) ---> 2N2(g) + 3CaCl2(s) + 6H2O(l)

Be careful with this reaction as side products can form wich are toxic (chloroamine and dichloroamine).
