Which of these is a balanced chemical equation?

Answer: option H
Explanation:
Balanced equation means that the no of atoms on both sides should be equal.
In H, Cl2 + 2NaBr-------> Br2 + 2NaCl
No of Cl atoms, 2=2
No of Br atoms, 2=2
And sodium atoms,2=2
Hence it is balanced equation
And remain are not balanced.
