so is this correct?

2KMnO4 + 3NaHSO3 -> 2MnO2(s) + 3Na2SO4(aq) + H+ + H2O

??

and so what about number 3? i know one of the products is MnO2 (s), i'm sort of lost on this question.

[quote="expert"]What is K2SOR?[/quote]
K2SO4**

so is 1 like this?

2KMnO4 + H2SO4 + 5NaHSO3 -> 2MnSO4 + 5K2SOR + Na2SO4 + 3H2O

??

and for 3, what should the other products be then? I know in this reaction MnO2 (s) is yielded for sure.

k i have the following, could you please tell me if I am correct? 1) H++2KMnO4(aq)+H2SO4(aq)+5NaHSO3(aq)->2MnSO4(aq)+5K2SO4(aq)+NaSO4(aq)+3H2O 2) 2KMnO4(aq)+3NaOH(aq) + NaHSO3(aq) -> K2SO4 +2K2MnO4(aq) + 2Na2SO4(aq) + 2H2O 3) 2KMnO4 + 3NaHSO3 -> 2MnO2(s)+ K2MnO4 (aq) + 3Na2SO4(aq) + H+ + H2O

post please!

Alright I am doing a lab about oxidation of manganese I need to find the products of these reactants and balance the chemical equation. This is what I have.
