H2+Br2

The reaction between hydrogen gas (H₂) and bromine gas (Br₂) produces hydrogen bromide (HBr). The balanced chemical equation for this reaction is:

\[ \text{H}_2(g) + \text{Br}_2(g) \rightarrow 2 \text{HBr}(g) \]

In this reaction, one molecule of hydrogen gas combines with one molecule of bromine gas to form two molecules of hydrogen bromide. This reaction is exothermic and occurs readily when the gases are mixed. If you have any more specific questions about this reaction or related topics, feel free to ask!
