Answer: The balanced chemical equation is given below.
Explanation:
Double-displacement reaction is defined as the reaction in which exchange of ions takes place. The general equation representing this reaction follows:
[tex]AB+CD\rightarrow CB+AD[/tex]
The balanced chemical equation for the reaction of barium hydroxide and perchloric acid follows:
[tex]Ba(OH)_2(aq.)+2HClO_4(aq.)\rightarrow Ba(ClO_4)_2(aq.)+2H_2O(l)[/tex]
By Stoichiometry of the reaction:
1 mole of barium hydroxide reacts with 2 moles of perchloric acid to produce 1 mole of barium chlorate and 2 moles of water molecule.
Hence, the balanced chemical equation is given above.
