Ionic equations and Spectator Ions question REALLY SHORT

amd123

1. The problem statement, all variables and given/known data
Pb(NO3)2(aq) + H2SO4(aq) → PbSO3(s) + HNO3(aq)
Pb + (NO3)2(aq) + H2 + SO4(aq) → PbSO3(s) + H + NO3(aq)

3. The attempt at a solution

So far I've done that, and now I'm stuck I see h2 and h can I cross out both or do i have to balance right now? My teacher said you can balance at the end. Can i cross out one h on the left and the remaining on the right?

Snazzy

H2 is a gas. H2SO4 (aq) only releases H+ ions.

amd123

can i get rid of them or no?

Could Snazzy be saying you won't get HNO3? rather H + NO3 ???

amd123

no i copied exactly the way it is from my prentice hall chem book hwork assignment

amd123

wait there is a problem
Pb(NO3)2(aq) + H2SO4(aq) → PbSO4(s) + HNO3(aq)
Pb + (NO3)2(aq) + H2 + SO4(aq) → Pb + SO4(s) + H + NO3(aq)

MichaelXY

To balance I think you get
Pb(NO3)2(aq) + H2SO4(aq) --> PbSO4(s) + 2HNO3(aq)

if that helps any.

ok
thanks

I know, not much help. Sorry :(
