Hi everyone!
This is my 1st post-I am taking an at home study chemistry class (grade 12 University level) so I can get into Nursing-Anyway, it has been a while since I have done chem so I need some *delete me*
Here's the question:
For each of the following situations, identify those for which a reaction is likely to occur.For those that do, write a net ionic equation.

a)Chrmium dipped into silver nitrate--I said yes
b) Gold immersed in hydrochloric acid-i said no
c)Nickel pellets dropped into calcium acetate --I don't know
d) Aluminum dropped into a bath of sulphuric acid -i said yes
e) Zinc dipped into a solution of lead(II)nitrate-i said no

Anyway, I have no idea if I am heading in the right direction--I am having a hard time figuring this out
PLEASE *delete me*!!

I'd check your last answer.  For both that and b think about the activity series of metals in solution.  Think about which of the two metals are more stable in the oxidized state (higher on the series)
