Ionic equations and Spectator Ions question REALLY SHORT

In summary, the conversation discusses balancing a chemical equation and specifically addresses the presence of H2 and H in the equation. The participants also consider the possibility of HNO3 being formed in the reaction and suggest a balanced equation to solve the problem.

Homework Statement


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?

H2 is a gas. H2SO4 (aq) only releases H+ ions.
 
  • #3
can i get rid of them or no?

Could Snazzy be saying you won't get HNO3? rather H + NO3 ?
 
  • #5
no i copied exactly the way it is from my prentice hall chem book hwork assignment

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)

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

if that helps any.

I know, not much help. Sorry :(
 

What are ionic equations and spectator ions?

Ionic equations are chemical equations that show the chemical reactions between ions in a solution. Spectator ions are ions that do not participate in the reaction and remain in the solution unchanged.

Why are ionic equations important?

Ionic equations allow us to focus on the important components of a chemical reaction and better understand the changes that occur.

How do you identify spectator ions?

Spectator ions can be identified by comparing the reactants and products in a chemical equation. If an ion is present on both sides and does not undergo a change, it is a spectator ion.

Can spectator ions be omitted from an ionic equation?

Yes, spectator ions can be omitted from an ionic equation because they do not play a role in the reaction and do not affect the overall outcome.

What is the purpose of balancing ionic equations?

Balancing ionic equations ensures that there is an equal number of atoms of each element on both sides of the equation, representing the law of conservation of mass.
