When the equation is correctly balanced, the coefficient of aluminum chloride will be ___.
AlCl3 (aq) + Ba(OH)2 (aq) → Al(OH)3 (s) + BaCl2 (aq)

The answer for the following question is answered below.

Therefore when the equation is balanced the co-efficient of aluminium chloride will be 2.

Explanation:

The balanced equation for the following equation is:

+  → +

To balance an equation:

When 2 moles of aluminium chloride react with 3 moles of barium hydroxide on the reactants side then on the products side it yields 2 moles of aluminium hydroxide and 3 moles of barium chloride

(i.e.)

2 + 3  → 2 + 3

Therefore when the equation is balanced the co-efficient of aluminium chloride will be 2.
