Chapter 14, Problem 25E

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

$\begin{array}{l}\text{a}{\text{. C+O}}_{\text{2}}\to {\text{CO}}_{\text{2}}\\ \text{b}{\text{. 2Na+Cl}}_{\text{2}}\to \text{2NaCl}\\ \text{c}{\text{. Mg+I}}_{\text{2}}\to {\text{MgI}}_{\text{2}}\end{array}$
