potassium nitrate reaction with hydrochloric acid? Answered

i recently mixed sugar and potassium nitrate to make a rocket. i ignited the mix and after it was done burning it left a molten pool of what i assume is potassium nitrate. i pored hydrochloric acid on the solidified pool and i produced a large amount of heat and was creating a brown-red gas. the gas was heavier than air because it sank to the bottom. can anyone tell me what this gas was?

Oops. I wrote the wrong formula there. Nitrogen dioxide is NO2 That's one nitrogen atom and two oxygen atoms.

Also, if you got your fuel mix right, the pool will have been a lot more than just potassium nitrate.
