Identify each reaction as combination / decomposition / combustion / single replacement / double replacement:

1) K2CO3 (s) → K2O (aq) + CO2 (g)

2) C2H4 (g) + 3 O2 (g) → 3 CO2 (g) + 2 H2O (g)

3) 2 LiOH (aq) + Pb(NO3)2 (aq) → 2 LiNO3 (aq) + Pb(OH)2 (s)

4) 2 Mg (l) + TiCl4 (g) → 2 MgCl2 (s) + Ti (s)

5) NH3 (g) + HCl (g) → NH4Cl (s)

6) Mg (s) + 2 HBr (aq) → MgBr2 (aq) + H2 (g)

7) CaSO3 (s) → CaO (s) + SO2 (g)

8) Hg2(NO3)2 (aq) + NaBr (aq) → Hg2Br2 (s) + 2 NaNO3 (aq)
