Answer:
Wavelength (typically measured in nanometers) is the distance between two points in a wave.Frequency (typically measured in Hertz) is the number of waves in a specific time . Frequency and wavelength have both direct and inverse relationships. The crucial difference between frequency and wavelength is that frequency shows the total number of wave oscillations in a given time. As against wavelength specifies the distance between two specific points of a wave.
Explanation:
Frequency is how often something changes per second be it amplitude of a voltage on a wire or be it the bobbing back and forth of a bobblehead. Frequency is how often something moves up and down in a second. If a bobble head moves forward and backward in one second then it has a bobbling frequency of 1 Hertz (Hz). The unit of frequency is Hertz (Hz) or # of cycles or oscillations per second. A wavelength is measured in distance like meters (m). For photons or light or radiowaves the equation is wavelength=speed of light/frequency.

Answer:
![T_b=-88.48\°C](https://tex.z-dn.net/?f=T_b%3D-88.48%5C%C2%B0C)
Explanation:
Hello,
In this case, since the entropy of vaporization is defined in terms of the enthalpy of vaporization and the boiling point of the given substance, nitrous oxide, as shown below:
![\Delta _{vap}S=\frac{\Delta _{vap}}{T_b}](https://tex.z-dn.net/?f=%5CDelta%20_%7Bvap%7DS%3D%5Cfrac%7B%5CDelta%20_%7Bvap%7D%7D%7BT_b%7D)
Solving for the boiling point of nitrous oxide, we obtain:
![T_b=\frac{\Delta _{vap}H}{\Delta _{vap}S}=\frac{16.53\frac{kJ}{mol}*\frac{1000J}{1kJ} }{89.51\frac{J}{mol} } \\ \\T_b=184.67K](https://tex.z-dn.net/?f=T_b%3D%5Cfrac%7B%5CDelta%20_%7Bvap%7DH%7D%7B%5CDelta%20_%7Bvap%7DS%7D%3D%5Cfrac%7B16.53%5Cfrac%7BkJ%7D%7Bmol%7D%2A%5Cfrac%7B1000J%7D%7B1kJ%7D%20%7D%7B89.51%5Cfrac%7BJ%7D%7Bmol%7D%20%7D%20%5C%5C%20%5C%5CT_b%3D184.67K)
Which in degree Celsius is also:
![Tb=184.67-273.15\\\\T_b=-88.48\°C](https://tex.z-dn.net/?f=Tb%3D184.67-273.15%5C%5C%5C%5CT_b%3D-88.48%5C%C2%B0C)
Best regards.
Answer:
See figure 1
Explanation:
For this question, we have to remember that in the lewis structures all atoms must have<u> 8 electrons</u>. And each atom would have a different value of <u>valence electrons</u>:
Carbon => 4
Oxygen=> 6
Hydrogen=> 1
Additionally, for the <u>hybridizations</u> we have to remember that:
=> 4 single bonds
=> 1 double bond
=> 1 double bond
With this in mind, the formaldehyde and formic acid would have
carbons and the ethanol an
carbon.
Finally, for the oxidation state. We have to remember that <u>if we have more bonds with oxygen, we will have more oxidation</u>. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).
See figure 1
I hope it helps!
A I believe should be right!
