For a spontaneous reaction \(\mathrm{A}(a q)+\mathrm{B}(a q) \longrightarrow \mathrm{A}^{-}(a q)+ \mathrm{B}^{+}(a q)\), answer the following questions:
(a) If you made a voltaic cell out of this reaction, what half reaction would be occurring at the cathode, and what half-reaction would be occurring at the anode?
(b) Which half-reaction from (a) is higher in potential energy?
(c) What is the sign of \(E_{\text {cell }}^{\circ}\)? [Section 20.3]

Chapter 1: Atoms 1.1 A Particulate View of the World: Structure Determines Properties matter is particulate/composed of particles structure of those particles determines the properties of matter matter: anything that occupies space and has mass atoms: basic particles that compose ordinary matter o smaller particles than matter molecules: atoms that bind together in a specific geometrical arrangement water molecules = really small and structure determines its properties o water is bent => if it’s linear, it’d have a lower boiling point; weakened attraction b/t molecules; easier to evaporate; solutes won’t dissolve as easily **change in structure = change in function and properties chemistry: science that seeks to understand the properties of matter 1.2 Classifying Matter: A Particulate View substance: a specific instance of matter (Ex: air, water or sand) state of matter: first classification (of matter) depends on relative positions of the particles and how strongly they interact with one another relative to temperature composition of matter: second classification that depends on the types of particles The States of Matter: Solid, Liquid, and Gas solids: matter that attracts to one another strongly and pack close to each other o has fixed volume and rigid shape liquids: matter that packs as close as particles in solid matter but w/ slightly weaker attractions o has fixed volume but not fixed s
