Chapter 8.3, Problem 20PP

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

$\begin{array}{l}a.H_2\left(g\right)+B{r}_2(I)\to 2HBr\left(g\right)\hfill \\ b.AgN{O}_3\left(aq\right)+NaCI\left(aq\right)\to AgCI\left(s\right)+NaN{O}_3\left(aq\right)\hfill \\ c.2H_2{O}_2\left(aq\right)\to 2H_{2}O\left(I\right)+{\text{ O}}_2\left(g\right)\hfill \\ d.Zn\left(s\right)+CuC{I}_2\left(aq\right)\to Cu\left(s\right)+ZnC{I}_2\left(aq\right)\hfill \\ e.C_5{H}_8(g)+7O_2\left(g\right)\stackrel{\Delta }{\to }5C{O}_2\left(g\right)+4H_{2}O\left(g\right)\hfill \end{array}$
