A mixture with medium sized particles that do not settle out is called

Chemistry

Alexandra [31]3 years ago
7 0

Answer: colloid

Explanation:

Colloids are solutions in which small sized particles are suspended throughout the solution as they do not settle own their own. Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.

Colloids are solutions with particle size intermediate between true solutions and suspensions. Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily. The particle size in colloids is less and hence they do not settle under the effect of gravity.

Pavlova-9 [17]

Answer:

The correct answer is -  intertidal zone, temperature fluctuations, clams

Explanation:

Intertidal zones are the region where rifts form between land and ocean due to the meet of low and high tides. This is also known as the seashore. These zones are the region with temperature fluctuation recorded.

This provides a better habitat that allows the organism to live in this zone. The organism that lives in intertidal zones is live in high numbers the example of organisms are clams and sea urchins.

Thus, the correct answer is -  intertidal zone, temperature fluctuations, clams.

Consider a system of nitrogen with temperature of 288k and pressure of 8 mpa what is the compressibility factor?
Alla [95]

The compressibility factor is 1.1.

Temperature of Nitrogen = 288 K

Pressure of Nitrogen = 8mpa

The ideal gas law's departure is compensated for by the compressibility factor (Z). An equation of state or industry correlation based on the following relationship is used to compute the compressibility factor:

                                            PV = ZRT

Z ~f (composition, P, T)

where,

Z = compressibility factor at P, T for a given composition.

P = absolute pressure.

T = temperature.

R = universal gas constant.

                             V = \frac{ZRT}{P}

                                 = (Z × 8.314 × 288) / 8 × 10⁷

                                 = (299.30 × 10⁻⁷) Z m³/kg

The reduced temperature is the ratio of the temperature of the gas to its critical temperature. Similarly, the reduced pressure is the ratio of the gas pressure to its critical pressure as described in the following equations:

T_r=\frac{T}{T_c} \\\\P_r=\frac{P}{P_c}

P – Absolute pressure of gas

T – Absolute temperature of gas

Tr – Reduced temperature

Pr – Reduced pressure

Tc – Critical temperature

Pc – Critical pressure

T_r= \frac{288}{126.2} = 2.3\\\\P_r = \frac{8}{3.39} = 2.3

Z = 1.1 (from the compressibility chart)

V = 329.23 10⁻⁷ m³/kg

Therefore, the compressibility factor is 1.1.
