Answer:
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.
<em>Lead nitrate + potassium iodide(?) ==> lead iodide(?) + potassium nitrate</em>
The volume of the gas that occupy at STP is 165. 28 cm^3
calculation
by use of combined gas law that is P1V1/T1=P2V2/T2, where
P1=84.6 kpa
T1=23.5 +273=296.5 K
V1=215 cm^3
At STP T= 273 K and P= 101.325 Kpa
therefore p2 = 101.325 Kpa and T2 = 272 K V2=?
by making V2 the subject of the formula V2 =T2P1V1/P2T1
V2 = 273 K x 84.6 Kpa x 215 cm^3/ 101,.325 Kpa x296.5 K =165.28 cm^3
