Answer:
The equation shows balance.
Step-by-step explanation:
You can easily count the number of elements on each side.
On the left side of the equation, you have 2 moles of Na and 2 moles of Cl.
On the right side of the equation, you also have 2 moles of Na and 2 moles of Cl because the two elements formed a compound meaning that whatever number is in front of them, both elements will receive the same number.
