Chapter 8.3, Problem 21PP

Classify each of the following as a combination, decomposition, single replacement, double replacement, or combustion reaction:

$\begin{array}{l}a.4Fe\left(s\right)+3O_2\left(g\right)\to 2F{e}_2{O}_3\left(s\right)\hfill \\ b.Mg\left(s\right)+2AgN{O}_3\left(aq\right)\to 2Ag\left(s\right)+Mg{\left(N{O}_3\right)}_2\left(aq\right)\hfill \\ c.CuC{O}_3\left(s\right)\to CuO\left(s\right)+C{O}_2\left(g\right)\hfill \\ d.A{l}_2{\left(S{O}_4\right)}_3\left(aq\right)+6KOH\left(aq\right)\to \hfill \\ ` 2A1{\left(OH\right)}_3\left(s\right)+3K_{2}S{O}_4\left(aq\right)\hfill \\ e.C_4{H}_8\left(g\right)+6O_2\left(g\right)\stackrel{\Delta }{\to }4C{O}_2\left(g\right)+4H_{2}O\left(g\right)\hfill \end{array}$
