Chapter 5, Problem 5.50P

Balance each equation.
a. $\text{Mg}\left(\text{s}\right)\text{ + HBr}\left(\text{aq}\right)\to {\text{MgBr}}_{\text{2}}\left(\text{s}\right){\text{ + H}}_{\text{2}}\left(\text{g}\right)$

b. $\text{CO}\left(\text{g}\right){\text{ + O}}_{\text{2}}\left(\text{g}\right)\to {\text{CO}}_{\text{2}}\left(\text{g}\right)$

c. $\text{PbS}\left(\text{s}\right){\text{ + O}}_{\text{2}}\left(\text{g}\right)\to \text{PbO}\left(\text{s}\right){\text{ + SO}}_{\text{2}}\left(\text{g}\right)$

d. ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\text{+ NaOH}\to {\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}{\text{+ H}}_{\text{2}}\text{O}$

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