State whether the following statements are true or false.
The importance of using H2 O2 cell in jet engines;
a)because it doesn't release gasses which cause Greenhouse Effect
b)because it doesn't release gasses which cause Ozone layer depletion
The answer key states b is false as the cell release H2O vapour which cause Greenhouse Effect.
But from what I've learned the reactions occur in the cell are as follows;
2 H2(g) + 4 OH^-(aq) --> 4H2O(l) + 4e
O2(g)+2H2O(l)+4e-->4 OH^-(aq)
Cell reaction :
2H2(g) + O2(g) -->2H2O(l)

Maybe the liquid water, is turning to vapour when the engine is active??
I agree
