Final Exam Q: Memorizing Polyatomic Ions

Postby Summer de Vera 2C » Sun Dec 02, 2018 3:19 pm

Hi! Should we memorize the formulas of all the polyatomic ions? I'm just asking because if we need to first write out the reactants and products for a reaction given the name of the molecule, I imagine we're gonna need to know the polyatomic ions. Thanks!

I don't think that we are going to have to memorize the polyatomic ions for the final as up to this point Professor Lavelle has not given off that impression. Also, on all of the past tests we have taken this has not been the case.

I don't believe you will have to memorize the names of all the polyatomic ions, but at this point in the course you should know the names of several of the molecules that we use regularly such as cyanide and carbonate. Other than that, the final is highly unlikely to have a section dedicated to just naming compounds, and any other naming questions will likely be folded into a question of compound composition or balancing chemical equations as you mentioned. Hope that helped!
