Chapter 14, Problem 26E

Draw Lewis structures for each chemical reaction, and identify what is oxidized and what is reduced:

$\begin{array}{l}\text{a}{\text{. 2K+Cl}}_{\text{2}}\to \text{2KCl}\\ \text{b}{\text{.4Al+3O}}_{\text{2}}\to {\text{2Al}}_{\text{2}}{\text{O}}_{\text{3}}\\ \text{c}{\text{. CH}}_{\text{4}}{\text{+2O}}_{\text{2}}\to {\text{CO}}_{\text{2}}{\text{+2H}}_{\text{2}}\text{O}\end{array}$
