The gas that is produced from the decomposition of hydrogen peroxide would be oxygen. Hydrogen peroxide (H2O2) would decompose into water (H2O) and oxygen (O2) where water is in a liquid state and oxygen is in the gas state at STP. When the smoldering toothpick would come in contact with the oxygen that is produced, it would start burning again or a combustion reaction would happen.
