Question

Reaction of br2 with na2co3 in aqueous solution gives sodium bromide

Answer 1

5 moles of sodium bromide molecules are produced in the given chemical reaction.

Explanation: For the reaction of bromine and sodium carbonate, the balanced chemical reaction will be:

3Br2 + 3Na2CO3 → 5NaBr + NaBrO3 + 3CO2

By Stoichiometry,

3 moles of bromine reacts with 3 moles of sodium carbonate to produce 5 moles of sodium bromide, 1 mole of sodium bromate and 3 moles of carbon dioxide gas.

From the above stoichiometry, it is visible that 5 moles of NaBr are produced in the given chemical reaction.
