Yes and no..... and apologies if i complicate the process but...
The BS/V chemical reaction actually occurs in two steps. First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3 → H2O + CO2
The carbon dioxide escapes the solution as bubbles.
No because there are a few steps in this reaction (wasted energy?).... Yes because the decomposition of the carbonic acid to CO2 is similar...
The decomposition of H2O2 under the presence of a catalyst (and/or heat) creates an Exothermic decomposition, some of which feeds back into the process, accelerating it. (self accelerating decomposition temperature). And of course steam (and o2)at that temperature expands rapidly (thru the nozzle). In a way, similar to using expanding steam in a loco engine (ok went to a railway museum today so still topical). Funny to think that way... a steam powered helicopter...
I seem to recall reading somewhere that weight for weight, the decomposition releases as much energy as dynamite. (will have to confirm that though!)
