ionic and net ionic equations
I need to write a balanced ionic equations and net ionic equations for 15 questions. Can you help start me off with these two. A precipitate of barium sulfate forms when aqeous solutions of barium nitrate and potassium sulfate are mixed. Zinc ion and hydrogen gas form when zinc metal reacts with aqu...

Grams and moles
I am totally stumped. Where do I begin? Ethyl acetate reacts with H2 in the presence of a catalyst to yield ethyl alcohol: C4H8O2(l) + H2(g) --- C2H6O(l) How do I balance an equation for this reaction? Then I need to figures out how many moles of ethyl alcohol are produced by reaction of 1.5 mol of ...

Net ionic equations
Here are three samples of the 30 I need to complete.
I need to find net ionic equations for the below reactions:
2 AuCl3(aq) + 3 Sn(s) --- 3 SnCl2(aq) + 2 Au (s)
2 Nal(aq) + Br2(l) --- 2 NaBR(aq) + I2 (s)
2 AgNO3(ag) + Fe(s) --- Fe(NO3)2(aq) + 2 Ag(s)
Thank you.
