This is a double replacement reaction which forms barium sulfate and salt (NaCl) when the sodium ions in sodium sulfate (mirabilite) remove chlorine from barium chloride.
Synthesis reaction because those two reactants combine to form a larger product. Ex A+B=AB like salt added to water to make salt water. Easy!
It's double replacement. Notice how the positive ions change positions.
This is an example of a synthesis reaction since these two elements form a compound.

This is a combination or synthesis reaction. 2 atoms of K (potassium) combine with a diatomic molecule I2 (iodine) to form two molecules of KI (potassium iodide).
Redox reaction.
The given reaction is an example of "synthesis" reaction, in particular one in which two elements react to form a chemical compound.
Pb(NO3)2 + 2KI ==> PbI2 + 2KNO3 is a precipitation reaction. The PbI2 is insoluble in water and will precipitate. It is NOT neutralization, because you do not have an acid reacting with a base.
Assuming a double displacement reaction. 2KI + BaS --> K2S + BaI2

2KI + HgCl₂ -----> 2KCl + HgI₂
2KI + F2 ----> 2KF + I2I hope this help :) :P :D :} :]
2ki+ h2so4 ----> k2so4 + 2hi
2KI + Cl2 = 2KCl + I2
Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
