Why are some solutes soluble in water and some solutes soluble in cyclohexane?

Chemistry
1 answer:
Elza [17]4 years ago
5 0
<h2>Answer:</h2>

Polar molecules can interact with the partial positive and partially negative part of polar solvents such water forming dipole dipole interactions and hence, can dissolve in water. Non-polar solute particles dissolve in non polar solvents such as cyclohexane through interactions such as Van Der Waals forces.

What is the mass of chlorine in 3.9 x 1019 molecules of Cl2?
Ray Of Light [21]

Explanation:

A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by

E=hf=hcλ(energy of a photon)E=hf=hcλ(energy of a photon),

where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful. Note that Planck’s constant in these units is h = 4.14 × 10−15 eV · s.

Since many wavelengths are stated in nanometers (nm), it is also useful to know that hc = 1240 eV · nm.

These will make many calculations a little easier.

All EM radiation is composed of photons. Figure 1 shows various divisions of the EM spectrum plotted against wavelength, frequency, and photon energy. Previously in this book, photon characteristics were alluded to in the discussion of some of the characteristics of UV, x rays, and γ rays, the first of which start with frequencies just above violet in the visible spectrum. It was noted that these types of EM radiation have characteristics much different than visible light. We can now see that such properties arise because photon energy is larger at high frequencies.

The temperature at which the vapor pressure of a liquid is equal to normal atmospheric pressure is the _______. A. boiling point
timurjin [86]

Answer:

A. boiling point

Explanation:

The correct answer is;

A. boiling point

The boiling point of a liquid is the temperature at which the vapour pressure is equal to the atmospheric pressure.

B. melting point

This option is wrong because the melting point is the temperature at which a solid undergoes a phase change to a liquid.

C. freezing point

This option is wrong because the freezing point is the temperature at which a liquid undergoes a phase change to a solid.
