Ba(HS)2+K2Cr2O7+H2SO4 = ?

To balance the chemical equation, we first need to write out the unbalanced equation:

Ba(HS)2 + K2Cr2O7 + H2SO4 → ?

Now, let's balance the equation:

Ba(HS)2 + K2Cr2O7 + H2SO4 → BaSO4 + Cr2(SO4)3 + K2SO4 + H2O

Therefore, the balanced chemical equation is:

Ba(HS)2 + K2Cr2O7 + H2SO4 → BaSO4 + Cr2(SO4)3 + K2SO4 + H2O
