Question

4. Which of the following equations is

balanced?
A. Cl2 + NaBr-> Br2 + NaCl
B. 2Cl2 + NaBr-> 2Br2 + NaCl
C. Cl2 + NaBr --> Br2 + 2NaCl
D. 2Cl2 + 2NaBr--> Br2 + NaCl2
E. Cl2 + 2NaBr-> Br2 + 2NaCl.
​

Answer 1

E. Cl2 + 2NaBr ----> Br2 + 2NaCl

Step-by-step explanation:

Number of Cl molecules is 2 on the reactant and product side of the equation.

Number of Na molecules is 2 on the reactant and product side of the equation.

Number of Br molecules is 2 on the reactant and the product side of the equation.

As the reactant side is equal to the product side, the equation is balanced.
