Chapter 5, Problem 31P

Balance each equation.
a. $\text{Ni}\left(\text{s}\right)\text{ + HCl}\left(\text{aq}\right)\to {\text{NiCl}}_{\text{2}}\left(\text{aq}\right){\text{ + H}}_{\text{2}}\left(\text{g}\right)$

b. ${\text{CH}}_{\text{4}}\left(\text{g}\right){\text{ + Cl}}_{\text{2}}\left(\text{g}\right)\to {\text{CCl}}_{\text{4}}\left(\text{g}\right)\text{ + HCl}\left(\text{g}\right)$

c. ${\text{KClO}}_{\text{3}}\to {\text{KCl +O}}_{\text{2}}$

d. ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}\text{ + HCl}\to {\text{AlCl}}_{\text{3}}{\text{ + H}}_{\text{2}}\text{O}$

e. $\text{Al}{\left(\text{OH}\right)}_{\text{3}}{\text{+ H}}_{\text{2}}{\text{SO}}_{\text{4}}\to {\text{A1}}_{\text{2}}{\left({\text{SO}}_{\text{4}}\right)}_{\text{3}}{\text{+ H}}_{\text{2}}\text{O}$
