If Chris Brown is nonpolar, and Karrueche is polar, do they mix? Why or why not?
The people cannot mingle with each other to produce an outcome (solution) therefore they do not mix.

How do you know when a reaction is completely balanced?
Balance this reaction.
(I'll write it)
The exothermic and endothermic sides must have the same number of moles of each atom.
2,1,1,2
400
What type of relationship does atomic radius and electronegativity have? Explain.
Inverse relationship.
As atomic radius increases going down a group, electronegativity decreases. The attraction level is low for electronegativity due to the increasing energy levels.
