Question

How do you balance `Na C l \rightarrow N a + C l _ { 2}`?

Answer 1

`2NaCl → 2Na + Cl_2`

Explanation:

`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!
