Reaction of Br_(2) with Na_(2)CO_(3) in aqueous solution gives NaBr and sodium bormate with evolution of CO_(2) gas. The number of NaBr molecue involved in the balanced chemical equation is ………….

Answer»


SOLUTION :`3Br_(2)+3Na_(2)CO_(3)overset(HOT)rarr 5NaBr+NaBrO_(3)+3CO`
`{:((i),[Br_(2)+overset(Θ)(O)Hoverset("Hot")toBr^(Θ)+BrO_(3)^(Θ)]),("Note:", "In cold it gives"),((ii), [Br_(2)+Ooverset(Θ)Hoverset("Cold")toBr^(Θ)+BRO^(Θ)]):}]` Both are disproportionation reaction
