Simple Displacement Reactions & Balancing Chemical Reactions

AI Thread Summary
In the discussion on simple displacement reactions, the focus is on balancing the reaction between copper and silver nitrate. The initial attempt suggested copper (I) nitrate and silver as products, but the correct answer is copper (II) nitrate and silver. The reasoning highlights that copper typically exists as Cu2+ in aqueous solutions, making it the more stable ion. The nitrate ion (NO3-) acts as a spectator and does not influence the oxidation state of copper in this reaction. Understanding the common oxidation states of elements is crucial for correctly balancing chemical reactions.

Homework Statement



Complete the simple displacement reactions and balance any chemical reactions.

Homework Equations



copper + silver nitrate → __________ + ____________

The Attempt at a Solution



Since copper on the periodic table can be Cu2+ or Cu+, my solution was
copper + silver nitrate → copper (I) nitrate + silver

The answer says: copper (II) nitrate. I don't know why this works when NO3- has a 1- charge.
 
Physics news on Phys.org
Cu2+ is the most common and most stable copper ion, especially in aqueous solutions. Charge on NO3- doesn't matter, as it is only a spectator.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
