Answer:
302.75 Liters
Explanation:
Given:
P = 1 atm
V = ?
n = 13.5 moles
R = 0.0821 atm x L / mole x K
T = 273.15 K
PV = nRT
(1) (V) = (13.5) (0.0821) (273.15)
V = 302.75 Liters
Answer:
Lead (II) iodide
Explanation:
The reaction of lead (II) nitrate, Pb(NO₃)₂ with KI is:
Pb(NO₃)₂(aq) + 2KI(aq) → KNO₃(aq) + PbI₂(s)
This is a typical double-replacement reaction where anions and cations exchange its couple.
All nitrates are solubles, thus, KNO₃ is not the precipitate.
The only possibility of precipitate is PbI₂,
Lead (II) iodide, a yellow and insoluble solid...
