PLS HELP! BRAINLIEST IF RIGHT WITH EXPLANATION :)

I'm going to have to go with double displacement. Sue me if I'm wrong.

Explanation:

Synthesis? No. There would have to be one product, not two.

Decomposition? No. There would have to be one reactant, not two.

Single displacement? No. There are two elements/compounds that are switching places.

Double displacement? Highly likely. From the reactants' side to the products' side, nitrate and iodine switch places.

Neutralization? Uh, I don't think so. I can't remember why, though.

Combustion? No. O₂ would have to be one of the reactants.

Lead nitrate + potassium iodide(?) ==> lead iodide(?) + potassium nitrate

if you mean hydrogen and oxygen then water is the product
