Answer: The mole ratio of [tex]Cl_2[/tex] to [tex]Br_2[/tex] in the given reaction is 1:1 .
Explanation: For a reaction the mole ratio is the ratio of their coefficients. Coefficients are the numbers used to balance the equations.
The given reaction is:
[tex]Cl2+2NaBr\rightarrow 2NaCl+Br_2[/tex]
In this equation, the coefficient for each of [tex]Cl_2[/tex] and [tex]Br_2[/tex] is 1. So, the mole ratio of [tex]Cl_2[/tex] to [tex]Br_2[/tex] in the given reaction is 1:1 .
