Is there any way to tell what the spectator ions will be??

I know if I see the complete reaction, I can easily eliminate the the elements that haven't changed from reactants to products, but I am having a difficult time

"prediciting the spectator ions" in the following reactions....

any advice please and thank you

Predicting the spectator ions requires that you know what will react and what won't in a reaction, assuming they just give you the reactants. There's really no way to tell a spectator ion from any other ion without knowing or having a good idea waht the products are.

That said, definitely know your solubility rules. Some ions are unreactive and are almost always spectator ions. Na+ and Cl- immediately come to mind.
