HURRY 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, O² or [OH]¹-)

2. Which ions are the spectator ions? (Be sure to include their ionic charges. For example, O² or [OH]¹-)

Different isotopes indicate that an element will have different numbers of

According to each substances heat of fusion, which of the items below requires more heat to be added per gram of substance to go from solid to liquid? silver sulfur water lead

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
