The balanced chemical reaction between methyl amine (CH3NH2) and hydrobromic acid (HBr) is:

CH3NH2(aq) + HBr(aq) → CH3NH3Br(aq)

Here's the breakdown:

* CH3NH2(aq): Methyl amine in aqueous solution.

* HBr(aq): Hydrobromic acid in aqueous solution.

* CH3NH3Br(aq): Methylammonium bromide, the salt formed from the reaction, also in aqueous solution.

The reaction is an acid-base reaction where:

* HBr acts as the acid, donating a proton (H+).

* CH3NH2 acts as the base, accepting the proton.

This results in the formation of the methylammonium ion (CH3NH3+) and the bromide ion (Br-), which combine to form the salt methylammonium bromide (CH3NH3Br).
