Question
1. Complete and balance each of the following double-replacement reactions. FeSO4(aq)+ Sr(OH)2(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if there is no reaction. 2. Write a balanced equation for each of the following single-replacement reactions. Sodium metal is added to acetic acid. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if there is no reaction. 3. Which of the following Au and Ir react with aqueous copper(II) nitrate.
Explanation / Answer
1) FeSO4(aq)+ Sr(OH)2(aq) ------------------------->Fe(OH)2 (s) + SrSO4 (s)
2) 2 Na (s) + 2 CH3COOH (aq) ------------------------> 2 CH3COONa (aq) + H2 (g)
3) Ir react with copper(II) nitrate. but not Au
the reason is that Ir standard reduction potential less than that of Cu. so Ir can replace Cu+2 but not Au
