Naddik [55]

Answer:

See Explanation

Explanation:

We can write the molecular orbital configuration of molecules in the same way as we write the orbital electron configuration of atoms. The valence electrons in the molecule are filled into molecular orbitals of appropriate energy in accordance to the Aufbau principle.

For CO;

σ2s2, σ*2s2, Π2py2, Π2pz2, σ2px2

For NO;

σ2s2, σ*2s2, Π2px2, Π2py2, σ2pz2, Π*2px1

For CN-;

σ2s2, σ*2s2, Π2px2, Π2py2, σ2pz2

These are the ground state electron configurations of these molecules.

Answer:

A and D takes much slower

Explanation:

Here, we want to select, out of the four given reactions, the one that is slower than the other two

The answers in these case are reactions 1 and 4 ( A and D)

The two reactions show what is called rust (as directly seen in reaction 4)

When we speak of rust, we simply mean a reaction that occurs over time

For example, non coated roofings of houses doesn’t get to change color at an instant

The color degradation that occurs is something that takes some time from the initial time they were used to roof the house

Hence, from these analogy, we can see that these reactions need an an external support to thrive or to come into existence

These external supports are natural forces and they contributing efforts occur over time and cannot be seen immediately

These reactions are thus ones that take much slower time than conventional laboratory reactions in the case of the formation of the precipitate or a reaction that requires a low flash point temperature such as that of black powder to produce such explosive effects

So in conclusion, what we are saying is that the two selected reactions are subjected to the availability of some conditions and may take time to manifest and these absolutely differentiates them from reactions that are spontaneous such as the one having an explosive effect or the other one leading to the formation of a precipitate which takes far less times

Answer:

Wavelength in high frequency waves:

Wavelength. Waves of blue light have a shorter wavelength than waves of red light. The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.

Wavelength in low frequency waves:

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
