Question

fill in the blanks to balance this chemical reaction.
____ li + __ alcl3 → __ licl + ____ al

Explanation:

Step1: Balance chlorine atoms

In \(AlCl_3\), there are 3 chlorine atoms. In \(LiCl\), there is 1 chlorine atom. To balance chlorine, we put a 3 in front of \(LiCl\). So the equation becomes \(Li+AlCl_3
ightarrow3LiCl + Al\).

Step2: Balance lithium atoms

Now, in \(3LiCl\), there are 3 lithium atoms. So we put a 3 in front of \(Li\). The equation is \(3Li+AlCl_3
ightarrow3LiCl + Al\).

Step3: Check aluminum atoms

On the left - hand side, there is 1 \(Al\) atom in \(AlCl_3\). On the right - hand side, there is 1 \(Al\) atom. So the equation is balanced.

Answer:

\(3\) \(Li+1\) \(AlCl_3
ightarrow3\) \(LiCl + 1\) \(Al\)
