Question

2. P redict the products for the following singlc and double displacement reactions, and write balanced molecular equations (including physical states) for each of them. If you predict that no reaction will occur, write "NR", followed by a brief explanation. a. Aluminum metal + aqueous silver acetate b. Aqueous zinc nitrate + aqueous lithium chloride c. Hydrobromic acid + solid magnesium sulfite d. Aqueous rubidium hydroxide +perchloric acid e. Tin metal +phosphoric acid f. Aqueous lithium chromate + aqueous gold(III) iodide Page 4 of 4

Explanation / Answer

a) Al(s) + 3CH3COOAg(aq) ----> Al(CH3COO)3( aq ) + 3Ag(s)

b) Zn(NO3)2(aq) + LiCl(aq) -----> No reaction

the products ZnCl2 and LiNO3 are possible to react Zn(NO3)2 and LiCl , so , there is no reaction

c) 2HBr(aq) + Na2SO3(s) ------> 2NaBr(aq) + SO2(g) + H2O(l)

d) RbOH(aq) + HClO4(l) ----------> RbClO4(s) + H2O(l)

e) 6Sn(s) + 2H3PO4(l) --------> 2Sn3(PO4)2(s) + 3H2(g)

f) 3Li2CrO4(aq) + 2AuI3(aq) ----> Au2(CrO4)3( s) + 6LiI(aq)
