Answer: Option (c) is the correct answer.
Explanation:
The given reaction is as follows.
Number of atoms on reactant side are as follows.
- Fe = 1
- Cl = 2
Number of atoms on product side are as follows.
- Fe = 1
- Cl = 3
To balance the given equation, we multiply Fe by 2 and by 3 on the reactant side. Therefore, the balanced chemical equation will be as follows.
Thus, the coefficient of is 3.
The number of liters of 3.00 M lead (II) iodide : 0.277 L
<h3>Further explanation</h3>Reaction(balanced)
Pb(NO₃)₂(aq) + 2KI(aq) → 2KNO₃(aq) + PbI₂(s)
moles of KI = 1.66
From the equation, mol ratio of KI : PbI₂ = 2 : 1, so mol PbI₂ :
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So the number of liters(V) of 3.00 M lead (II) iodide-PbI₂ (n=0.83, M=3):
