Chapter 5.2, Problem 5.2P

Balance the following equations:

(a)     $\text{Ca}{\left(\text{OH}\right)}_{\text{2}}\text{+}\text{HCl}\to {\text{CaCl}}_{\text{2}}\text{+}{\text{H}}_{\text{2}}\text{O}$

(b)     $\text{Al}+{\text{O}}_2\to {\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}$

(c)     ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{3}}+{\text{O}}_{\text{2}}\to {\text{CO}}_{\text{2}}+{\text{H}}_{\text{2}}\text{O}$

(d)     ${\text{AgNO}}_{\text{3}}\text{+}{\text{MgCl}}_{\text{2}}\to \text{AgCl}\text{+}\text{Mg}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$
