#2NaCl → 2Na + Cl_2#

#NaCl → Na + Cl_2#

To balance this equation, we make the number of each element the same on both sides.

So Left Hand Side
Na= 1
Cl=1

And Right Hand Side
Na=1
Cl=2

We balance the Cl first by placing a 2 in front of the NaCl
#2NaCl → Na + Cl_2#

We now have
LHS
Na=2 Cl= 2

RHS
Na=1 Cl=2

So now we need to balance the Na by placing a 2 in front of it
#2NaCl → 2Na + Cl_2#

LHS
Na=2 Cl=2

RHS
Na=2 Cl=2

Success!
