1. When aqueous solutions of lead (II) nitrate (Pb(NO3)2) and sulfuric acid (H2SO4) react, lead (II) sulfate forms as a precipitate.
Identify the spectator
ions and write a balanced net ionic equation for this reaction.

Which ions combine to form the precipitate? (Be sure to include their ionic
charges. For example, o? or [OH]1- )

Which ions are the spectator ions?

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
