Hydrogen Bromide - an overview | ScienceDirect Topics

Hydrogen bromide was bubbled into a solution of 39 (0.128 g, 0.5 6 mmol) in Et 2 O (45 mL) over a period of 2 h. Initially, the mixture was kept at 0 °C, but as the reaction proceeded, it was allowed to gradually warm to rt. Saturated aqueous NaHCO 3 (10 mL) was carefully added, followed by solid sodium carbonate, until no further gas evolution was observed.

Hydrogen fuel - Wikipedia

In a flame of pure hydrogen gas, burning in air, the hydrogen (H 2) reacts with oxygen (O 2) to form water (H 2 O) and releases energy. 2H 2 (g) + O 2 (g) → 2H 2 O (g) + energy If carried out in atmospheric air instead of pure oxygen, as is usually the case, hydrogen coustion may yield small amounts of nitrogen oxides , along with the water vapor.
