Question

How is dihydrogen oxidized by dihalogen to give a hydrogen halide?

Answer 1

Garbage in must equal garbage out......

Explanation:

`1/2H_2(g) + 1/2X_2(s) rarr HX(g)`

`X=Cl, Br, I..........`

If the half-integral stoichiometric coefficient offends your sensibilities, then double both sides.......

`H_2(g) + I_2(g) rarr 2HI(g)`

Mass is conserved, and charge is conserved.
