Question

Write and balance the equation for the decomposition of aluminum chloride into its elements. phase symbols are optional.

Answer 1

The 3 and 2 to the right of the components are subscriptions.

Answer 2

Explanation:

A balanced equation is an equation in which number of molecules on both left and right side are the same or equal.

When aluminium chloride decomposes then it gives aluminium and chlorine gas.

The decomposition reaction will be as follows.

        $2AlCl_{3} (s) \rightarrow 2Al(s) + 3Cl_{2}(g)$

Therefore, we can see that number of molecules on the reactant and product side are same. Hence, this equation is balanced.
