Starting with aluminum, describe with balanced equations how you would prepare (a) Al2Cl6, (b) Al2O3, (c) Al2(SO4)3, (d) NH4Al(SO4)2 · 12H2O.
(a)

Interpretation:
The balanced equations for the given aluminum compounds has to be described.
Concept introduction:
- There is a law for conversion of mass in a chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants.
- The concept of writing a balanced chemical equation is depends on conversion of reactants into products.
- First write the reaction from the given information.
- Then count the number of atoms of each element in reactants as well as products.
- Finally obtained values could place it as coefficients of reactants as well as products.
Answer to Problem 21.51QP
The balanced equation for preparation of
Explanation of Solution
To write the balanced equation for preparation of
We can produce
Here, the reaction is unbalanced. So we need to balance it. To balance the reaction, calculate the number of atoms present in left side and right side. Finally, obtained values could place it as coefficients of reactants as well as products. The balanced equation is
