You are assigned the task of separating a desired granular material, with a density of 3.26 g/cm3, from an undesired granular ma

terial that has a density of 2.04 g/cm3. You want to do this by shaking the mixture in a liquid. A solid will float on any liquid that is more dense. Using an Internet-based source, find the densities of the following substances: carbon tetrachl oride, hexane, benzene, and diiodomethane. Which of these liquids will serve your purpose, assuming no chemical interaction between the liquid and the solids?

Answer:

diiodomethane

Explanation:

The densities of each of the liquids mentioned in the question are stated below;

CCl4- 1.59 g/cm^3

Hexane- 0.672 g/cm^3

Benzene- 0.8765 g/cm^3

Diiodomethane- 3.3 g/cm^3

Clearly, the density of diiodomethane methane is almost the same as that of the desired granular material, hence the undesired granular material having a density of 2.04 g/cm3 will float in diiodomethane thus separating the two granular materials.

bija089 [108]

Answer:

The answer to your question is  V2 = 867.3 mL

Explanation:

Data

Volume 1 = V1 = 400 ml

Temperature 1 = T1 = 22°C

Pressure 1 = P1 = 760 mmHg

Volume 2 = V2 = ?

Temperature 2 = T2 = 30°C

Pressure 2 = P2 = 360 mmHg

Process

1.- Convert Celsius to Kelvin

T1 = 22 + 273 = 295°K

T2 = 30 + 273 = 303°K

2.- Use the Combined gas law

              P1V1/T1 = P2V2/T2

- Solve for V2

            V2 = P1V1T2 / T1P2

- Substitution

            V2 = (760 x 400 x 303) / (295 x 360)

- Simplification

            V2 = 92112000 / 106200

-Result

            V2 = 867.3 mL

lesya [120]
Global warming affects many processes in biological ecosystems. Different species of flora and fauna change their habitats and geographical areas according to climate change and specific geographical environments. Areas of occurrence of specific species, for example insects in terrestrial areas and fish and arthropods in the seas and oceans, change. Bird habitats change, so migrations of some bird species may also be subject to modification. In the situation when forest areas dry out and turn into steppes and deserts, changes in natural habitats and areas of occurrence of species change and concern simultaneously many species of flora and fauna.

Can someone plz help me on question 3 I really need help plz

1. <em>Describe</em>

Frequency (f) and wavelength (λ) are inversely related.

f ∝ 1/λ

As one goes up, the other goes down and vice versa.

2. <em>Infer </em>

The frequency of infrared light is less than that of red light, so infra could mean something like less than or below or beneath.

Ultrahigh frequencies are extremely high compared with those of visible light. Ultrasound has frequencies that are far beyond what we can hear. An ultracentrifuge goes at extremely high speed, and an ultramicroscope can “see” tiny structures. Ultra could probably mean something like extremely or far beyond.

3. <em>Analyze </em>

Energy is directly proportional to frequency (E ∝ f).

Frequency is inversely proportional to wavelength (f ∝ 1/λ).

Energy is inversely proportional to wavelength (E ∝ 1/λ).

Read the given expression.
vovangra [49]

The variable X is the effective nuclear charge, and it remains constant down a group.

Discussion:

The effective nuclear charge is referred to as the actual amount of positive (nuclear) charge experienced by an electron in a polyelectronic atom.

The effective nuclear charge experienced by an electron is otherwise called the core charge.

It is mathematically evaluated as the difference in the atomic number and the core electrons. and since elements in the same group have equal number of Valence electrons, the effective nuclear charge is constant down the group.
