Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO3 and HI are mixed.

D)
I had
MgSO3 + 2HI - H2SO3 + MgI2

Mg + SO3 + 2H + 2I - 2H + SO3 + Mg + 2I

but correct answer is
2 H+(aq) + SO3 (aq) → H2O(l) + SO2(g)

How do I know when something becomes a gas or liquid?

chmvijay · Answer

is H2 SO3 is neutral
or balnced please check

chmvijay · Answer

H2SO4 is ok what about H2SO3????is it charge balanced molecule

anonymous · Answer

where you getting H2SO4 from ?

chmvijay · Answer

no just asking H2SO4 is balanced right

chmvijay · Answer

H2SO3 -2 should come right

chmvijay · Answer

bcoz one less O in it compared to H2 SO4

anonymous · Answer

Okay, Is this is a decomposition reaction because  H2 + SO3 decomposes to  H2O + SO2 ?

preetha · Answer

Yes, this is one of those random things they expect you to remember.  H2CO3 will also dissociate like that into H2O and CO2. When you have a gas as a product,then that will remain in the net ionic equation, as will H2O(l).
