# How would you balance Na(s) + Cl2 → NaCl(s)?

##### 1 Answer

The balanced equation is

#### Explanation:

**How to Balance the Equation #"Na(s)"+"Cl"_2("g")"##rarr##"NaCl"#.**

Since there are two chlorine atoms on the left side, there needs to be two chlorine atoms on the right side. So I put a coefficient of two in front of the formula

Now there are two sodium and two chlorine atoms on the right side. However, the left side has only one sodium atom. So I put a coefficient of two in front of the formula

Now there are two sodium and two chlorine atoms on both sides of the equation and it is balanced.

Notice that I only changed the amount of each substance by changing the coefficients. I did not change the formulas.
