Final answer:
To balance the given reaction: H₂SnCl6 + H₂S → SnS2 + HCl, the correct coefficients are: H₂SnCl6 + 3H₂S → SnS2 + 6HCl.
Step-by-step explanation:
To balance the given reaction: H₂SnCl6 + H₂S → SnS2 + HCl, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here are the correct coefficients:
H₂SnCl6 + 3H₂S → SnS2 + 6HCl
