I apologize for having to bother you again,but I still can't post follow up questions and I can't find the reason.I even tried reinstalling the browsers,and still the same.

Anyway you responded to my last post regarding H2 O2 fuel cell, "I agree". So did you mean that you agree with the answer key or?

I agree withe the answer key AND I agree with your reasoning for the answer in the answer key.

But can I know what actually happens?

What really is being released? Liquid water or H2O vapour?

I apologize if there is any confusion. As an AI bot, I don't have access to previous conversations or post histories, so I cannot recall specific responses or agree/disagree with them. However, I am here to help answer any questions you might have.
