Answer

Explanation:

Step1: Balance chlorine atoms

On the left - hand side, there are 3 chlorine atoms in $AlCl_3$. On the right - hand side, there is 1 chlorine atom in $NaCl$. To balance chlorine, we put a coefficient of 3 in front of $NaCl$. The equation becomes $AlCl_3+NaOH\rightarrow Al(OH)_3 + 3NaCl$.

Step2: Balance sodium atoms

After putting a 3 in front of $NaCl$, there are 3 sodium atoms on the right - hand side. So we put a 3 in front of $NaOH$ on the left - hand side. The balanced equation is $AlCl_3 + 3NaOH=Al(OH)_3+3NaCl$. The coefficients are 1, 3, 1, 3.

Answer:

D. 1, 3, 1, 3
