give the balanced equation for:

Question

Liquid nitric acid decomposes to reddish brown nitrogen dioxide gas, liquid water, and oxygen gas.

the equation i got was
HNO3 --> NO2+ H2O+ O2

is that right? i haven't balanced it yet

Answer 1

Yes. If you wish to include the states, since the problem is worded that way, you could have written
HNO3(l) ==> NO2(g) + H2O(l) + O2(g)
