Question

Complete and balance the equation for this single displacement reaction phases are optional cl2 nabr

Answer 1

Hey there!

It is a single- displacement reaction , so  by  balancing  the above equation:

2 NaBr + Cl2 = 2 NaCl+ Br2

Answer 2

Answer:

Cl₂(g) + 2NaBr(aq) = 2NaCl (aq) + Br₂(g)

Explanation:

Cl₂(g) + NaBr(aq) = NaCl (aq) + Br₂(g)

Here the chlorine replaces bromine from sodium bromide to form sodium chloride. Here aq stands for the aqueous phase and g stands for the gas phase.  

Balanced chemical equation:

Cl₂(g) + 2NaBr(aq) = 2NaCl (aq) + Br₂(g)

In the unbalanced there are two Cl atoms on the reactant side and one Cl atom on the product so to balance the equation we place a two before NaCl on the product side. Similarly, in the unbalanced there are two Br atoms on the reactant side and one Cl atom on the product so to balance the equation we place a two before NaCl on the product side.
