Step 1
Decomposition reactions are chemical reactions where a single compound breaks down into two or more simpler compounds.

Here are five examples of decomposition reactions:

Step 2
:

This reaction is catalyzed by various substances, such as manganese dioxide (MnO_2):

Final Answer

The five examples of decomposition reactions are: 1. H_2 O_2(aq) \longrightarrow H_2 O(l) + \frac{1}{2}O_2(g) 2. 2HgO(s) \longrightarrow 2Hg(l) + O_2(g) 3. 2Pb(NO_3)_2(s) \longrightarrow 2PbO(s) + 4NO_2(g) + O_2(g) 4. 2AgCl(s) \longrightarrow 2Ag(s) + Cl_2(g) 5. CaCO_3(s) \longrightarrow CaO(s) + CO_2(g)
