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):
Answer: option A) Mixtures may be composed of two or more elements, two or more compounds, or a combination of both.
Explanation:
A mixture is a combination of two or more substances mixed together and can be separated by physical methods.
A combination of two elements or compounds will yield chemical compounds NOT a mixture.
Thus, option A is false statement
The only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.
<h3>What is a triangle?</h3>
A triangle can be defined as a one of the plane shapes which has three sides and three angles
So therefore, the only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.
