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-)

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
