VMariaS [17]3 years ago
4 0

Answer:

6

Explanation

every p sublevel holds up to 6 electrons

so the 4p sublevel  must hold up to 6 electonsr

If one mole of a substance has a mass of 56.0 g, what is the mass of 11 nanomoles of the substance? Express your answer in nanog
9966 [12]

Answer:

616,0 ng is the right answer.

Explanation:

You should know that 1 mole = 1 .10^9 nanomoles

Get the rule of three.

1 .10^9 nanomoles ...................... 56.0 gr

11 nanomoles .....................

(11 x 56) / 1 .10^9 nanomoles = 6.16 x 10^-7 gr

Let's convert

6.16 x 10^-7 gr x 1 .10^9 = 616 ngr

Which of the following could happen when infrared radiation is absorbed by a molecule ?
Leto [7]

Answer:

       E) Intramolecular bond angles change

Explanation:

Infrared Radiation:

IR is electromagnetic radiations. The wavelength i.e. 700nm to 1000 mm of infrared is longer than invisible light and Its frequency is lower than light, that's why it is invisible to light.

  • When IR radiation strike the molecule it absorbed by this molecule.
  • This radiation used to identify and study chemicals.
  • Infrared radiation interact with intra-bonds of the molecule.
  • Bonds in the molecules have vibrational translational and rotational movements
  • Due to these vibration, rotation and translation movement it absorb a radiation of specific frequency and wavelength
  • These movements of bond are very small and absorbs radiations of very low frequency
  • So when Infrared light or radiation absorbed the intra-bonds of the molecule get affected and angles of these bonds changes.
  • As the frequency of the absorbed radiation matches the frequency of the bond that vibrates.

So

The correct option is option E

       E) Intramolecular bond angles change

* Note:

it couldn't be option A as the frequency of IR is not enough to rotate a whole molecule

It Couldn't be option B as IR rations are electromagnetic radiation of longer wave length so it one can not see it with light so how it will glow a molecule

It also not could be the option C as for the excitation of electrons require much higher energy.

It also not the option D as nuclear magnetic spin is associated with nuclear magnetic radiation that are much different from IR.
