Classify each of the reactions described by the following chemical equations as combination, decomposition, single replacement, or double replacement. (a) $2 \mathrm{KClO}_{3}(s) \rightarrow 2 \mathrm{KCl}(s)+3 \mathrm{O}_{2}(g)$ (b) $\mathrm{V}_{2} \mathrm{O}_{5}(s)+5 \mathrm{Ca}(l) \rightarrow 2 \mathrm{~V}(l)+5 \mathrm{CaO}(s)$ (c) $2 \mathrm{NaCl}(s)+\mathrm{H}_{2} \mathrm{SO}_{4}(l) \rightarrow 2 \mathrm{HCl}(g)+\mathrm{Na}_{2} \mathrm{SO}_{4}(s)$ (d) $\mathrm{Fe}(s)+2 \operatorname{HBr}(a q) \rightarrow \mathrm{FeBr}_{2}(a q)+\mathrm{H}_{2}(g)$
