1. The problem statement, all variables and given/known data I know that the process of fermentation occurs in two steps, however, in the second step where glucose/sucrose is broken down into ethanol and carbon dioxide, is the carbon dioxide expelled as a gas or in an aqueous state? (I'm assuming water is involved here) 2. Relevant equations [itex] C_6 H_12 O_6 (aq) \rightarrow 2C_2 H_5 OH (l) + 2CO_2 (?) [/itex] 3. The attempt at a solution Well, I'm going to take a stab in the dark and say its in an aqueous state, then escapes as gas as the solution settles down.
