The answer to your question is: c
Explanation:
A descomposition reaction is a chemical reaction in which the only one reactant yields two or more products.
a) HCl + NaHCO3 → H2O + CO2 + NaCl
This is not a descomposition reaction because there are two reactants not one, this option is incorrect.
b) 2Na + Cl2 → 2NaCl
THis option is also incorrect because there are two reactants in descompositin reaction there is only one reactant.
c) 2HgO → 2Hg + O2
There are only one reactant that yields 2 products, this is a descomposition reaction.
d) AgNO3 + NaCl → AgCl + NaNO3
THis is not a descomposition reaction because there are two reactants.
