Pb(NO3)2(aq) + H2SO4(aq) → PbSO3(s) + HNO3(aq)
Pb + (NO3)2(aq) + H2 + SO4(aq) → PbSO3(s) + H + NO3(aq)
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?
