What are the missing coefficients for this skeleton equation? al2(so4)3(aq) + koh(aq) ? al(oh)3(aq) + k2so4(aq?

The coefficients are 1, 6, 2 and 3

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.  

This also means that total mass on the reactant side must be equal to the total mass on the product side.

For the given chemical reaction, the balanced equation follows:

By Stoichiometry of the reaction:

1 mole of aqueous solution of aluminium sulfate reacts with 6 moles of aqueous solution of potassium hydroxide to produce 2 moles of aqueous solution of aluminium hydroxide and 3 moles of aqueous solution of potassium sulfate

Hence, the coefficients are 1, 6, 2 and 3
