The answer to the question is "B. Roman Numerals"
Pizza because the ingredients arent mixed together completely. you can clearly see the different ingredients as compared to the others
Chemical reaction: 2PCl₃ + O₂ → 2POCl₃.
m(PCl₃) = 194 g.
n(PCl₃) = m(PCl₃) ÷ M(PCl₃).
n(PCl₃) = 194 g ÷ 137,33 g/mol.
n(PCl₃) = 1,412 mol.
From chemical reaction: n(PCl₃) : n(POCl₃) = 1 : 1.
n(POCl₃) = 1,412 mol.
V(POCl₃) = n(POCl₃) · Vm.
V(POCl₃) = 1,412 mol · 22,4 mol/dm³.
V(POCl₃) = 31,64 dm³ at normal pressure and temperature.
Sample cost = $15.796
<h3>Further explanation</h3>
Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Answer: Homogenized milk is a colloid mixture.
Explanation: The particle size of homogenized milk is in between a solution which is much bigger but quite smaller enough than suspensions.
