Answer:
[tex]3H_2S+2Ga(ClO_3)_3\rightarrow Ga_2S_3+6HClO_3[/tex]
Explanation:
Hello,
In this case, the described chemical reaction is:
[tex]H_2S+Ga(ClO_3)_3\rightarrow Ga_2S_3+HClO_3[/tex]
After balancing, we must assure the same quantity of atoms of all the elements at both reactants and products:
[tex]3H_2S+2Ga(ClO_3)_3\rightarrow Ga_2S_3+6HClO_3[/tex]
Thus, we find two galliums, three sulfurs, six chlorines, six hydrogens and eighteen oxygens at both reactants and products.
Best regards.
