For each of the reactions below, classify as a combination, decomposition, single replacement, or double replacement.
Hg(NO3)2(aq) + 2NaI(aq) ⟶ HgI2(s) + 2NaNO3(aq)
AgNO3(aq) + NaCl(aq) ⟶ AgCl(s) + NaNO3(aq)
Zn(s) + H2SO4(aq) ⟶ ZnSO4(aq) + H2(g)
H2CO3(aq) ⟶ CO2(g) + H2O(l)
Hg(NO3)2(aq) + 2NaI(aq) ⟶ HgI2(s) + 2NaNO3(aq) - Double replacement
AgNO3(aq) + NaCl(aq) ⟶ AgCl(s) + NaNO3(aq) - Double replacement
Zn(s) + H2SO4(aq) ⟶ ZnSO4(aq) + H2(g) - Single replacement
H2CO3(aq) ⟶ CO2(g) + H2O(l) - Decomposition
