I think the best answer is b): it contains particles that can settle out. The definition of suspension is a heterogeneous (that is same in all parts) mixture that contains particles that could undergo sedimentation (settle down) - this definition is close to b). It should not matter whether those particles are nutrients( so A or C are not good answers).

0.908 L.Explanation:Firstly, we should calculate the number of moles of 1.60 g argon.n of Ar = mass / molar mass of Ar = (1.60 g) / (39.948 g/mol) = 0.04 mol.|t is established and known that the molar volume of a gas at STP (Standard Temperature and Pressure) is equal to 22.4 L for 1 mole of any ideal gas at a temperature of 273.15 K and a pressure of 1.00 atm. using cross multiplication:1.0 mole of Ar gas will occupy → 22.7 L0.04 mole of Ar gas will occupy → ??? L∴ The volume occupied by Ar = (0.04 mole) (22.7 L) / (1.0 mole) = 0.908 L.

Consider a Carnot cycle in which the working substance is 0.10 mol of perfect gas molecules, the temperature of the hot source is 373 K, and that of the cold sink is 273 K; the initial volume of gas is 1.00 dm3 , which doubles over the course of the first isothermal stage. For the reversible adiabatic stages it may be assumed that VT3/2 = constant. A) calculate the volume of the gas VB and Vc). B) calculate the volume of the gas after stage 3 (VD) by considering the reversible adiabatic compression from the starting point. C) for each of the four stages of the cycle, calculate the heat transferred to or from the gas. D) Explain why the work done is equal to the difference between the heat extracted from the hot source and that deposited in the cold sink. E) calculate the work done over the cycle and hence the efficiency n. F) confirm that your answer agrees with the efficiency from n = 1-Tc/Th).

Questions

Blood is considered a suspension because it contains particles that can settle out. A (heterogeneous) suspension is defined as a mixture between a liquid and particles of a solid. In the case, the particles do not dissolve. The particles and the liquid are mixed up so that the particles are dispersed throughout the liquid. They are "suspended" in the liquid. A key characteristic of a suspension is that the solid particles will settle and separate over time if left alone. This is exactly what happens when anti-coagulated blood is left to stand alone for some time. Blood cells separate and settle from the plasma, the watery part of the blood.
