I wanted to ask, let say:-
Situation A
1M of Acetic Acid + x amount of Sodium Bicarbonate(Baking Soda)

Situation B
3M of Acetic Acid + x amount of Sodium Bicarbonate(Baking Soda)

From the above situations, 2 different concentration of a same acid, one is triple(Yes, to be exact is TRIPLE) the concentration of the other one and mix with a SAME amount of Sodium Bicarbonate, will reaction make a big difference in terms of :-

1. The amount of CO2 gas produced

2. (Important question)The pressure produced if both reactions are being carried out in a bottle stucked with a rubber stopper.

3. The pressure produce to move an object from the nozzle(To be exact, 1st..the bottle is shaken to enable the reaction take place, the nozzle is still CLOSE(to build up the pressure), after around 10-15 seconds, the nozzle is open, will it create a big difference in terms of pressure of CO2 gas pushes out through the nozzle if using 1M and 3M of Acetic Acid and will it a ble to move a model car with load of 100ml of water + the bottle on the car?)

Thanks

OMG cheesenium, can you please guide me more on tat CO2 car competition....ahhhhhhhhhh.....juz tat this time the competition for the 1st time cannot have liquid leakage, meaning that when u pop the bottle, the liquid cannot flow out along with the gas, if not disqualified...btw, its Taylor's CO2 Model Car Competition, I'm really lost now @@ and the competition is on this friday T_______T

no le >_<
