Question

10HI + 2KMnO4 + 3H2SO4 -> 5I2 + 2MnO4 + K2SO4 + 8H2O

According to the balanced equation above, how many miles of HI would be necessary to produce 2.5 mol of I2, starting with 4.0 mil of KMnO4 and 3.0 mol og H2SO4?

Answer 1

Because if n(I2)=2,5 moles, for the reaction n(HI)=5 moles, n(KMnO4)=1 moles, n(H2SO4)=1,5 moles.

The start neede moles determine
