When their is decomposition of benzene .how water is formed in that process? |
|
Answer» Answer: Explanation: (First off, I am no professor so I am not REALLY sure) Benzene has a formula of C6H6 so heating of benzene at very high temperatures in the presence of oxygen should yield this- 2 C6H6 + 15 O2 –› 12 CO2 + 6 H2O As you can see the Benzene has been oxidized by the oxygen to form water and carbon di-oxide. Hence in the decomposition of benzene water is formed. Mark me brainliest if HELPS :) |
