2 NaCl + Br2 → 2 NaBr2 + Cl2

Answer 1

2 H2O → 2 H2 + O2 — Decomposition

Na + Cl → NaCl — Synthesis (combination)

C3H8 + 5 O2 → 3 CO2 + 4 H2O — Combustion

MgBr2 + 2 NaCl → MgCl2 + 2 NaBr — Double displacement (double replacement)

2 NaCl + Br2 → 2 NaBr + Cl2 — Single displacement (single replacement)
