If Species A converts CH$_4$ to CO$_2$, which process would Species B undertake? O The reduction of SO$_4^{2-}$ to S$^{2-}$, since the conversion of CH$_4$ to CO$_2$ is an reduction. O The reduction of S$^{2-}$ to SO$_4^{2-}$, since the conversion of CH$_4$ to CO$_2$ is an reduction. O The reduction of SO$_4^{2-}$ to S$^{2-}$, since the conversion of CH$_4$ to CO$_2$ is an oxidation. O The reduction of S$^{2-}$ to SO$_4^{2-}$, since the conversion of CH$_4$ to CO$_2$ is an oxidation.

[10 pts] In a 3D unit cell, an atom at a corner counts as 1/8th of an atom (because corners of unit cells are where 8 unit cells meet). For similar reasons, an atom on an edge (away from a corner) counts at 1/4th of an atom, an atom in a face (away from an edge) counts as 1/2 of an atom, and of course an atom inside the unit cell counts as 1. (a) For the first unit cell shown below what is the stoichiometry of the crystal? In other words, what are n, m, and p in the formula $A_mB_nX_p$? (b) Same question for the second unit cell shown below. A B X A B X

Each unit of a product can be made on either machine A or machine B. The nature of the machines makes their cost functions differ. Machine A $C(x) = 20 + \frac{x^2}{6}$ Machine B: $C(y) = 240 + \frac{y^2}{9}$ Total cost is given by $C(x,y) = C(x) + C(y)$. How many units should be made on each machine in order to minimize total costs if $x + y = 17,030$ units are required? The minimum total cost is achieved when units are produced on machine A and units are produced on machine B (Simplify your answer.)
