Chapter 7, Problem 91AP

Classify the reactions represented by the following unbalanced equations by as many methods as possible. Balance the equations.

msp;  ${\text{I}}_4{\text{O}}_9\left(s\right)\to {\text{I}}_2{\text{O}}_6\left(s\right)+{\text{I}}_2\left(s\right)+{\text{O}}_2\left(g\right)$

msp;  $\text{Mg}\left(s\right)+{\text{AgNO}}_3\left(aq\right)\to \text{Mg}{\left({\text{NO}}_3\right)}_2\left(aq\right)+\text{Ag}\left(s\right)$

msp;  ${\text{SiCl}}_4\left(l\right)+\text{Mg}\left(s\right)\to {\text{MgCl}}_2\left(s\right)+\text{Si}\left(s\right)$

msp;  ${\text{CuCl}}_2\left(aq\right)+{\text{AgNO}}_3\left(aq\right)\to \text{Cu}{\left({\text{NO}}_3\right)}_2\left(aq\right)+\text{AgCl}\left(s\right)$

msp;  $\text{Al}\left(s\right)+{\text{Br}}_2\left(l\right)\to {\text{AlBr}}_3\left(s\right)$
