Question

F2(g) + Ga2O(aq) →


Plz help

Answer 1

Answer:

6F2 ( g ) + 2Ga2O ( aq ) → 4GaF3 + O2

F is more reactive than O, so F displaces O from Ga2O and forms GaF3.

Ga has a valency of 3, it need 3 electrons to get complete electronic configuration.

F has a valency of 1,

3 F atoms constitutes 3 electrons.

So, GaF3.

And hence, the chemical equation is balanced on both sides.
