Types of reaction - 1 | Chemical Reactivity

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)
