Battery or electrochemical cell

Explanation:

A battery is a power source that directs electrons from oxidation - reduction reactions to flow through a device to give electrical power.

  • A battery is an electrochemical cell.
  • Electrochemical cells are devices in which chemical reactions produce an electric current that is, chemical energy is turned into electrical energy.
  • The reactions here are spontaneous redox reactions, hence electrons flows on its own in an external circuit.

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?
andreev551 [17]

Answer: The frequency of the wave is 0.5 hertz.

Explanation:

\nu =\frac{c}{\lambda }

\nu = Frequency of the wave

c = speed of the light in m/s

\lambda = Wavelength of the wave.

Here in question we are given with speed of the infrared light. So, we will replace the value of speed of light(c) from the given value of the speed of the infrared light.

Speed of infrared light = 6 m/s

\nu =\frac{\text{speed of infrared light}}{\lambda }=\frac{6 m/s}{12 m}=0.5 hertz

The frequency of the wave is 0.5 hertz.

Rank the following in terms of decreasing miscibility in C₈H₁₈ (octane), a major component of gasoline:
Aleksandr-060686 [28]

Answer:

In order of decreasing miscibility

C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)

Explanation:

The solubility of a solid is a measure of its ability to dissolve in a liquid while for liquids,  the miscibility is a measure of thhe liquid to mix with anoyjer liquid resulting in a soltion which can hold any amount of either liquids. Immiscible liquids are those that are not soluble or have very limited solibility with each other.

C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)

In the order of decreasing miscibility as like dissolve like, ability to dissociate and polar and organic characteristics are considered

In order to reduce the exposure to organic solvents like turpentine, some art instructors recommend the students clean brushes a
kykrilka [37]
Generally speaking, organic molecules tend to dissolve in solvents that have similar physical properties. A good rule of thumb is that "like dissolves like". Meaning, polar compounds can dissolve polar compounds and nonpolar compounds can dissolve nonpolar compounds.

To apply this to the current problem, we are told that the brushes are being cleaned with vegetable oil or mineral oil. In this case, the oils are used as solvents. In order for these solvents to be effective, the compounds they are trying to dissolve must be similar in structure and properties to other oils. Therefore, vegetable oil or mineral oil will be most effective in removing oil-based paints, as these will have the similar properties needed to dissolve in the oil solvents.
