Synthesis
a.
C3H8 + 5 O2 → 3 CO2 + 4 H2O
b.
MgBr2 + 2 NaCl → MgCl2 + 2 NaBr
c.
Na + Cl → NaCl
d.
2 H2O → 2 H2 + O2
e.
2 NaCl + Br2 → 2 NaBr2 + Cl2
a. The synthesis reaction between propane (C3H8) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O).
b. The synthesis reaction between magnesium bromide (MgBr2) and sodium chloride (NaCl) produces magnesium chloride (MgCl2) and sodium bromide (NaBr).
c. The synthesis reaction between sodium (Na) and chlorine (Cl) produces sodium chloride (NaCl).
d. The decomposition reaction of water (H2O) produces hydrogen gas (H2) and oxygen gas (O2).
e. The synthesis reaction between sodium chloride (NaCl) and bromine (Br2) produces sodium bromide (NaBr) and chlorine gas (Cl2).
